C# Class SharpCifs.Smb.SmbFile

This class represents a resource on an SMB network.

This class represents a resource on an SMB network. Mainly these resources are files and directories however an SmbFile may also refer to servers and workgroups. If the resource is a file or directory the methods of SmbFile follow the behavior of the well known Sharpen.FilePath class. One fundamental difference is the usage of a URL scheme [1] to specify the target file or directory. SmbFile URLs have the following syntax:

 smb://[[[domain;]username[:password]@]server[:port]/[[share/[dir/]file]]][?[param=value[param2=value2[...]]]

This example:

 smb://storage15/public/foo.txt

would reference the file foo.txt in the share public on the server storage15. In addition to referencing files and directories, jCIFS can also address servers, and workgroups.

Important: all SMB URLs that represent workgroups, servers, shares, or directories require a trailing slash '/'.

When using the java.net.URL class with 'smb://' URLs it is necessary to first call the static jcifs.Config.registerSmbURLHandler(); method. This is required to register the SMB protocol handler.

The userinfo component of the SMB URL (domain;user:pass) must be URL encoded if it contains reserved characters. According to RFC 2396 these characters are non US-ASCII characters and most meta characters however jCIFS will work correctly with anything but '@' which is used to delimit the userinfo component from the server and '%' which is the URL escape character itself.

The server component may a traditional NetBIOS name, a DNS name, or IP address. These name resolution mechanisms and their resolution order can be changed (See Setting Name Resolution Properties). The servername and path components are not case sensitive but the domain, username, and password components are. It is also likely that properties must be specified for jcifs to function (See Setting JCIFS Properties). Here are some examples of SMB URLs with brief descriptions of what they do:

[1] This URL scheme is based largely on the SMB Filesharing URL Scheme IETF draft.

SMB URL Examples
URL	Description
`smb://users-nyc;miallen:mypass@angus/tmp/`	This URL references a share called `tmp` on the server `angus` as user `miallen` who's password is `mypass`.
`smb://Administrator:P%40ss@msmith1/c/WINDOWS/Desktop/foo.txt`	A relativly sophisticated example that references a file `msmith1`'s desktop as user `Administrator`. Notice the '@' is URL encoded with the '%40' hexcode escape.
`smb://angus/`	This references only a server. The behavior of some methods is different in this context(e.g. you cannot `delete` a server) however as you might expect the `list` method will list the available shares on this server.
`smb://myworkgroup/`	This syntactically is identical to the above example. However if `myworkgroup` happends to be a workgroup(which is indeed suggested by the name) the `list` method will return a list of servers that have registered themselves as members of `myworkgroup`.
`smb://`	Just as `smb://server/` lists shares and `smb://workgroup/` lists servers, the `smb://` URL lists all available workgroups on a netbios LAN. Again, in this context many methods are not valid and return default values(e.g. `isHidden` will always return false).
`smb://angus.foo.net/d/jcifs/pipes.doc`	The server name may also be a DNS name as it is in this example. See Setting Name Resolution Properties for details.
`smb://192.168.1.15/ADMIN$/`	The server name may also be an IP address. See <a href="../../../resolver.html">Setting Name Resolution Properties for details.
`smb://domain;username:password@server/share/path/to/file.txt`	A prototypical example that uses all the fields.
`smb://myworkgroup/angus/ <-- ILLEGAL`	Despite the hierarchial relationship between workgroups, servers, and filesystems this example is not valid.
`smb://server/share/path/to/dir <-- ILLEGAL`	URLs that represent workgroups, servers, shares, or directories require a trailing slash '/'.
`smb://MYGROUP/?SERVER=192.168.10.15`	SMB URLs support some query string parameters. In this example the `SERVER` parameter is used to override the server name service lookup to contact the server 192.168.10.15 (presumably known to be a master browser) for the server list in workgroup `MYGROUP`.

A second constructor argument may be specified to augment the URL for better programmatic control when processing many files under a common base. This is slightly different from the corresponding java.io.File usage; a '/' at the beginning of the second parameter will still use the server component of the first parameter. The examples below illustrate the resulting URLs when this second contructor argument is used.

Examples Of SMB URLs When Augmented With A Second Constructor Parameter
First Parameter	Second Parameter	Result
`smb://host/share/a/b/`	`c/d/`	`smb://host/share/a/b/c/d/`
`smb://host/share/foo/bar/`	`/share2/zig/zag`	`smb://host/share2/zig/zag`
`smb://host/share/foo/bar/`	`../zip/`	`smb://host/share/foo/zip/`
`smb://host/share/zig/zag`	`smb://foo/bar/`	`smb://foo/bar/`
`smb://host/share/foo/`	`../.././.././../foo/`	`smb://host/foo/`
`smb://host/share/zig/zag`	`/`	`smb://host/`
`smb://server/`	`../`	`smb://server/`
`smb://`	`myworkgroup/`	`smb://myworkgroup/`
`smb://myworkgroup/`	`angus/`	`smb://myworkgroup/angus/ <-- ILLEGAL (But if you first create an SmbFile with 'smb://workgroup/' and use and use it as the first parameter to a constructor that accepts it with a second String parameter jCIFS will factor out the 'workgroup'.)`

Instances of the SmbFile class are immutable; that is, once created, the abstract pathname represented by an SmbFile object will never change.

Public Methods

Method	Description
CanRead ( ) : bool	Tests to see if the file this `SmbFile` represents can be read. Tests to see if the file this `SmbFile` represents can be read. Because any file, directory, or other resource can be read if it exists, this method simply calls the `exists` method.
CanWrite ( ) : bool	Tests to see if the file this `SmbFile` represents exists and is not marked read-only. Tests to see if the file this `SmbFile` represents exists and is not marked read-only. By default, resources are considered to be read-only and therefore for `smb://`, `smb://workgroup/`, and `smb://server/` resources will be read-only.
Connect ( ) : void	It is not necessary to call this method directly. It is not necessary to call this method directly. This is the `URLConnection` implementation of `connect()`.
CopyTo ( SmbFile dest ) : void	This method will copy the file or directory represented by this `SmbFile` and it's sub-contents to the location specified by the `dest` parameter. This method will copy the file or directory represented by this `SmbFile` and it's sub-contents to the location specified by the `dest` parameter. This file and the destination file do not need to be on the same host. This operation does not copy extended file attibutes such as ACLs but it does copy regular attributes as well as create and last write times. This method is almost twice as efficient as manually copying as it employs an additional write thread to read and write data concurrently. It is not possible (nor meaningful) to copy entire workgroups or servers.
CreateNewFile ( ) : void	Create a new file but fail if it already exists. Create a new file but fail if it already exists. The check for existance of the file and it's creation are an atomic operation with respect to other filesystem activities.
CreateTime ( ) : long	Retrieve the time this `SmbFile` was created. Retrieve the time this `SmbFile` was created. The value returned is suitable for constructing a System.DateTime object (i.e. seconds since Epoch 1970). Times should be the same as those reported using the properties dialog of the Windows Explorer program. For Win95/98/Me this is actually the last write time. It is currently not possible to retrieve the create time from files on these systems.
Delete ( ) : void	This method will delete the file or directory specified by this `SmbFile`. This method will delete the file or directory specified by this `SmbFile`. If the target is a directory, the contents of the directory will be deleted as well. If a file within the directory or it's sub-directories is marked read-only, the read-only status will be removed and the file will be deleted.
Equals ( object obj ) : bool	Tests to see if two `SmbFile` objects are equal. Tests to see if two `SmbFile` objects are equal. Two SmbFile objects are equal when they reference the same SMB resource. More specifically, two `SmbFile` objects are equals if their server IP addresses are equal and the canonicalized representation of their URLs, minus authentication parameters, are case insensitivly and lexographically equal. For example, assuming the server `angus` resolves to the `192.168.1.15` IP address, the below URLs would result in `SmbFile`s that are equal. smb://192.168.1.15/share/DIR/foo.txt smb://angus/share/data/../dir/foo.txt
Exists ( ) : bool	Tests to see if the SMB resource exists. Tests to see if the SMB resource exists. If the resource refers only to a server, this method determines if the server exists on the network and is advertising SMB services. If this resource refers to a workgroup, this method determines if the workgroup name is valid on the local SMB network. If this `SmbFile` refers to the root `smb://` resource `true` is always returned. If this `SmbFile` is a traditional file or directory, it will be queried for on the specified server as expected.
GetAttributes ( ) : int	Return the attributes of this file. Return the attributes of this file. Attributes are represented as a bitset that must be masked with `ATTR_*` constants to determine if they are set or unset. The value returned is suitable for use with the `setAttributes()` method.
GetCanonicalPath ( ) : string	Returns the full URL of this SMB resource with '.' and '..' components factored out. Returns the full URL of this SMB resource with '.' and '..' components factored out. An `SmbFile` constructed with the result of this method will result in an `SmbFile` that is equal to the original.
GetContentLength ( ) : int	This URLConnection method just returns the result of `length()`. This URLConnection method just returns the result of `length()`.
GetDate ( ) : long	This URLConnection method just returns the result of `lastModified`. This URLConnection method just returns the result of `lastModified`.
GetDfsPath ( ) : string	If the path of this `SmbFile` falls within a DFS volume, this method will return the referral path to which it maps. If the path of this `SmbFile` falls within a DFS volume, this method will return the referral path to which it maps. Otherwise `null` is returned.
GetDiskFreeSpace ( ) : long	This method returns the free disk space in bytes of the drive this share represents or the drive on which the directory or file resides. This method returns the free disk space in bytes of the drive this share represents or the drive on which the directory or file resides. Objects other than `TYPE_SHARE` or `TYPE_FILESYSTEM` will result in 0L being returned.
GetHashCode ( ) : int	Computes a hashCode for this file based on the URL string and IP address if the server. Computes a hashCode for this file based on the URL string and IP address if the server. The hashing function uses the hashcode of the server address, the canonical representation of the URL, and does not compare authentication information. In essance, two `SmbFile` objects that refer to the same file should generate the same hashcode provided it is possible to make such a determination.
GetInputStream ( ) : InputStream	This URLConnection method just returns a new `SmbFileInputStream` created with this file. This URLConnection method just returns a new `SmbFileInputStream` created with this file.
GetLastModified ( ) : long	This URLConnection method just returns the result of `lastModified`. This URLConnection method just returns the result of `lastModified`.
GetName ( ) : string	Returns the last component of the target URL. Returns the last component of the target URL. This will effectively be the name of the file or directory represented by this `SmbFile` or in the case of URLs that only specify a server or workgroup, the server or workgroup will be returned. The name of the root URL `smb://` is also `smb://`. If this `SmbFile` refers to a workgroup, server, share, or directory, the name will include a trailing slash '/' so that composing new `SmbFile`s will maintain the trailing slash requirement.
GetOutputStream ( ) : OutputStream	This URLConnection method just returns a new `SmbFileOutputStream` created with this file. This URLConnection method just returns a new `SmbFileOutputStream` created with this file.
GetParent ( ) : string	Everything but the last component of the URL representing this SMB resource is effectivly it's parent. Everything but the last component of the URL representing this SMB resource is effectivly it's parent. The root URL `smb://` does not have a parent. In this case `smb://` is returned.
GetPath ( ) : string	Returns the full uncanonicalized URL of this SMB resource. Returns the full uncanonicalized URL of this SMB resource. An `SmbFile` constructed with the result of this method will result in an `SmbFile` that is equal to the original.
GetPrincipal ( ) : Principal	Returns the `NtlmPasswordAuthentication` object used as credentials with this file or pipe. Returns the `NtlmPasswordAuthentication` object used as credentials with this file or pipe. This can be used to retrieve the username for example: `String username = f.getPrincipal().getName();` The `Principal` object returned will never be `null` however the username can be `null` indication anonymous credentials were used (e.g. some IPC$ services).
GetSecurity ( ) : Ace[]	Return an array of Access Control Entry (ACE) objects representing the security descriptor associated with this file or directory. Return an array of Access Control Entry (ACE) objects representing the security descriptor associated with this file or directory. Initially, the SIDs within each ACE will not be resolved however when `getType()`, `getDomainName()`, `getAccountName()`, or `toString()` is called, the names will attempt to be resolved. If the names cannot be resolved (e.g. due to temporary network failure), the said methods will return default values (usually `S-X-Y-Z` strings of fragments of). Alternatively `getSecurity(true)` may be used to resolve all SIDs together and detect network failures.
GetSecurity ( bool resolveSids ) : Ace[]	Return an array of Access Control Entry (ACE) objects representing the security descriptor associated with this file or directory. Return an array of Access Control Entry (ACE) objects representing the security descriptor associated with this file or directory. If no DACL is present, null is returned. If the DACL is empty, an array with 0 elements is returned.
GetServer ( ) : string	Retrieve the hostname of the server for this SMB resource. Retrieve the hostname of the server for this SMB resource. If this `SmbFile` references a workgroup, the name of the workgroup is returned. If this `SmbFile` refers to the root of this SMB network hierarchy, `null` is returned.
GetShare ( ) : string	Retrieves the share associated with this SMB resource. Retrieves the share associated with this SMB resource. In the case of `smb://`, `smb://workgroup/`, and `smb://server/` URLs which do not specify a share, `null` will be returned.
GetShareSecurity ( bool resolveSids ) : Ace[]	Return an array of Access Control Entry (ACE) objects representing the share permissions on the share exporting this file or directory. Return an array of Access Control Entry (ACE) objects representing the share permissions on the share exporting this file or directory. If no DACL is present, null is returned. If the DACL is empty, an array with 0 elements is returned. Note that this is different from calling `getSecurity` on a share. There are actually two different ACLs for shares - the ACL on the share and the ACL on the folder being shared. Go to Computer Management > System Tools > Shared Folders > Shares and look at the Properties for a share. You will see two tabs - one for "Share Permissions" and another for "Security". These correspond to the ACLs returned by `getShareSecurity` and `getSecurity` respectively.
GetType ( ) : int	Returns type of of object this `SmbFile` represents. Returns type of of object this `SmbFile` represents.
GetUncPath ( ) : string	Retuns the Windows UNC style path with backslashs intead of forward slashes. Retuns the Windows UNC style path with backslashs intead of forward slashes.
IsDirectory ( ) : bool	Tests to see if the file this `SmbFile` represents is a directory. Tests to see if the file this `SmbFile` represents is a directory.
IsFile ( ) : bool	Tests to see if the file this `SmbFile` represents is not a directory. Tests to see if the file this `SmbFile` represents is not a directory.
IsHidden ( ) : bool	Tests to see if the file this SmbFile represents is marked as hidden. Tests to see if the file this SmbFile represents is marked as hidden. This method will also return true for shares with names that end with '$' such as `IPC$` or `C$`.
LastModified ( ) : long	Retrieve the last time the file represented by this `SmbFile` was modified. Retrieve the last time the file represented by this `SmbFile` was modified. The value returned is suitable for constructing a System.DateTime object (i.e. seconds since Epoch 1970). Times should be the same as those reported using the properties dialog of the Windows Explorer program.
Length ( ) : long	Returns the length of this `SmbFile` in bytes. Returns the length of this `SmbFile` in bytes. If this object is a `TYPE_SHARE` the total capacity of the disk shared in bytes is returned. If this object is a directory or a type other than `TYPE_SHARE`, 0L is returned.
List ( ) : string[]	List the contents of this SMB resource. List the contents of this SMB resource. The list returned by this method will be; files and directories contained within this resource if the resource is a normal disk file directory, all available NetBIOS workgroups or domains if this resource is the top level URL `smb://`, all servers registered as members of a NetBIOS workgroup if this resource refers to a workgroup in a `smb://workgroup/` URL, all browseable shares of a server including printers, IPC services, or disk volumes if this resource is a server URL in the form `smb://server/`, or `null` if the resource cannot be resolved.
List ( ISmbFilenameFilter filter ) : string[]	List the contents of this SMB resource. List the contents of this SMB resource. The list returned will be identical to the list returned by the parameterless `list()` method minus filenames filtered by the specified filter.
ListFiles ( ) : SmbFile[]	List the contents of this SMB resource as an array of `SmbFile` objects. List the contents of this SMB resource as an array of `SmbFile` objects. This method is much more efficient than the regular `list` method when querying attributes of each file in the result set. The list of `SmbFile`s returned by this method will be; files and directories contained within this resource if the resource is a normal disk file directory, all available NetBIOS workgroups or domains if this resource is the top level URL `smb://`, all servers registered as members of a NetBIOS workgroup if this resource refers to a workgroup in a `smb://workgroup/` URL, all browseable shares of a server including printers, IPC services, or disk volumes if this resource is a server URL in the form `smb://server/`, or `null` if the resource cannot be resolved.
ListFiles ( ISmbFileFilter filter ) : SmbFile[]	List the contents of this SMB resource. List the contents of this SMB resource. The list returned will be identical to the list returned by the parameterless `listFiles()` method minus filenames filtered by the specified filter.
ListFiles ( ISmbFilenameFilter filter ) : SmbFile[]	List the contents of this SMB resource. List the contents of this SMB resource. The list returned will be identical to the list returned by the parameterless `listFiles()` method minus files filtered by the specified filename filter.
ListFiles ( string wildcard ) : SmbFile[]	The CIFS protocol provides for DOS "wildcards" to be used as a performance enhancement. The CIFS protocol provides for DOS "wildcards" to be used as a performance enhancement. The client does not have to filter the names and the server does not have to return all directory entries. The wildcard expression may consist of two special meta characters in addition to the normal filename characters. The '' character matches any number of characters in part of a name. If the expression begins with one or more '?'s then exactly that many characters will be matched whereas if it ends with '?'s it will match that many characters or less*. Wildcard expressions will not filter workgroup names or server names. winnt> ls c?o clock.avi -rw-- 82944 Mon Oct 14 1996 1:38 AM Cookies drw-- 0 Fri Nov 13 1998 9:42 PM 2 items in 5ms
Mkdir ( ) : void	Creates a directory with the path specified by this `SmbFile`. Creates a directory with the path specified by this `SmbFile`. For this method to be successful, the target must not already exist. This method will fail when used with `smb://`, `smb://workgroup/`, `smb://server/`, or `smb://server/share/` URLs because workgroups, servers, and shares cannot be dynamically created (although in the future it may be possible to create shares).
Mkdirs ( ) : void	Creates a directory with the path specified by this `SmbFile` and any parent directories that do not exist. Creates a directory with the path specified by this `SmbFile` and any parent directories that do not exist. This method will fail when used with `smb://`, `smb://workgroup/`, `smb://server/`, or `smb://server/share/` URLs because workgroups, servers, and shares cannot be dynamically created (although in the future it may be possible to create shares).
RenameTo ( SmbFile dest ) : void	Changes the name of the file this `SmbFile` represents to the name designated by the `SmbFile` argument. Changes the name of the file this `SmbFile` represents to the name designated by the `SmbFile` argument. Remember: `SmbFile`s are immutible and therefore the path associated with this `SmbFile` object will not change). To access the renamed file it is necessary to construct a new `SmbFile`.
SetAttributes ( int attrs ) : void	Set the attributes of this file. Set the attributes of this file. Attributes are composed into a bitset by bitwise ORing the `ATTR_*` constants. Setting the value returned by `getAttributes` will result in both files having the same attributes.
SetCreateTime ( long time ) : void	Set the create time of the file. Set the create time of the file. The time is specified as milliseconds from Jan 1, 1970 which is the same as that which is returned by the `createTime()` method. This method does not apply to workgroups, servers, or shares.
SetLastModified ( long time ) : void	Set the last modified time of the file. Set the last modified time of the file. The time is specified as milliseconds from Jan 1, 1970 which is the same as that which is returned by the `lastModified()`, `getLastModified()`, and `getDate()` methods. This method does not apply to workgroups, servers, or shares.
SetReadOnly ( ) : void	Make this file read-only. Make this file read-only. This is shorthand for `setAttributes( getAttributes() \| ATTR_READ_ONLY )`.
SetReadWrite ( ) : void	Turn off the read-only attribute of this file. Turn off the read-only attribute of this file. This is shorthand for `setAttributes( getAttributes() & ~ATTR_READONLY )`.
SmbFile ( SmbFile context, string name ) : System	Constructs an SmbFile representing a resource on an SMB network such as a file or directory. Constructs an SmbFile representing a resource on an SMB network such as a file or directory. The second parameter is a relative path from the `parent SmbFile`. See the description above for examples of using the second `name` parameter.

Constructs an SmbFile representing a resource on an SMB network such as a file or directory. The second parameter is a relative path from the `context`. See the description above for examples of using the second `name` parameter. The `shareAccess` parameter controls what permissions other clients have when trying to access the same file while this instance is still open. This value is either `FILE_NO_SHARE` or any combination of `FILE_SHARE_READ`, `FILE_SHARE_WRITE`, and `FILE_SHARE_DELETE` logically OR'd together.

Method Details

CanRead() public method

Tests to see if the file this SmbFile represents can be read.

Tests to see if the file this SmbFile represents can be read. Because any file, directory, or other resource can be read if it exists, this method simply calls the exists method.

public CanRead ( ) : bool
return	bool

CanWrite() public method

Tests to see if the file this SmbFile represents exists and is not marked read-only.

Tests to see if the file this SmbFile represents exists and is not marked read-only. By default, resources are considered to be read-only and therefore for smb://, smb://workgroup/, and smb://server/ resources will be read-only.

public CanWrite ( ) : bool
return	bool

Connect() public method

It is not necessary to call this method directly.

It is not necessary to call this method directly. This is the URLConnection implementation of connect().

public Connect ( ) : void
return	void

CopyTo() public method

This method will copy the file or directory represented by this SmbFile and it's sub-contents to the location specified by the dest parameter.

This method will copy the file or directory represented by this SmbFile and it's sub-contents to the location specified by the dest parameter. This file and the destination file do not need to be on the same host. This operation does not copy extended file attibutes such as ACLs but it does copy regular attributes as well as create and last write times. This method is almost twice as efficient as manually copying as it employs an additional write thread to read and write data concurrently.

It is not possible (nor meaningful) to copy entire workgroups or servers.

SmbException

public CopyTo ( SmbFile dest ) : void

CreateNewFile() public method

Create a new file but fail if it already exists.

Create a new file but fail if it already exists. The check for existance of the file and it's creation are an atomic operation with respect to other filesystem activities.

public CreateNewFile ( ) : void
return	void

CreateTime() public method

Retrieve the time this SmbFile was created.

Retrieve the time this SmbFile was created. The value returned is suitable for constructing a System.DateTime object (i.e. seconds since Epoch 1970). Times should be the same as those reported using the properties dialog of the Windows Explorer program. For Win95/98/Me this is actually the last write time.

Equals() public method

Tests to see if two SmbFile objects are equal.

Tests to see if two SmbFile objects are equal. Two SmbFile objects are equal when they reference the same SMB resource. More specifically, two SmbFile objects are equals if their server IP addresses are equal and the canonicalized representation of their URLs, minus authentication parameters, are case insensitivly and lexographically equal.

For example, assuming the server angus resolves to the 192.168.1.15 IP address, the below URLs would result in SmbFiles that are equal.

 smb://192.168.1.15/share/DIR/foo.txt smb://angus/share/data/../dir/foo.txt

Initially, the SIDs within each ACE will not be resolved however when getType(), getDomainName(), getAccountName(), or toString() is called, the names will attempt to be resolved. If the names cannot be resolved (e.g. due to temporary network failure), the said methods will return default values (usually S-X-Y-Z strings of fragments of).

Alternatively getSecurity(true) may be used to resolve all SIDs together and detect network failures.

Note that this is different from calling getSecurity on a share. There are actually two different ACLs for shares - the ACL on the share and the ACL on the folder being shared. Go to Computer Management > System Tools > Shared Folders > Shares and look at the Properties for a share. You will see two tabs - one for "Share Permissions" and another for "Security". These correspond to the ACLs returned by getShareSecurity and getSecurity respectively.

The CIFS protocol provides for DOS "wildcards" to be used as a performance enhancement.

The CIFS protocol provides for DOS "wildcards" to be used as a performance enhancement. The client does not have to filter the names and the server does not have to return all directory entries.

The wildcard expression may consist of two special meta characters in addition to the normal filename characters. The '*' character matches any number of characters in part of a name. If the expression begins with one or more '?'s then exactly that many characters will be matched whereas if it ends with '?'s it will match that many characters or less.

Wildcard expressions will not filter workgroup names or server names.
