You can use mount to mount Network File System (NFS) network shares.


mount [-o <Option>[...]] [-u:<UserName>] [-p:{<Password> | *}] {\\<ComputerName>\<ShareName> | <ComputerName>:/<ShareName>} {<DeviceName> | *}


The mount command-line utility mounts the file system identified by ShareName exported by the NFS server identified by ComputerName and associates it with the drive letter specified by DeviceName or, if an asterisk (*) is used, by the first available driver letter. Users can then access the exported file system as though it were a drive on the local computer. When used without options or arguments, mount displays information about all mounted NFS file systems.

The mount utility is available only if Client for NFS is installed.

The following options and arguments can be used with the mount utility.

Term Definition

-o rsize=<buffersize>

Sets the size in kilobytes of the read buffer. Acceptable values are 1, 2, 4, 8, 16, and 32; the default is 32 KB.

-o wsize=<buffersize>

Sets the size in kilobytes of the write buffer. Acceptable values are 1, 2, 4, 8, 16, and 32; the default is 32 KB.

-o timeout=<seconds>

Sets the time-out value in seconds for a remote procedure call (RPC). Acceptable values are 0.8, 0.9, and any integer in the range 1-60; the default is 0.8.

-o retry=<number>

Sets the number of retries for a soft mount. Acceptable values are integers in the range 1-10; the default is 1.

-o mtype={soft | hard}

Sets the mount type (default is soft). Regardless of the mount type, mount will return if it cannot immediately mount the share. Once the share has been successfully mounted, however, if the mount type is hard, Client for NFS will continue to try to access the share until it is successful. As a result, if the NFS server is unavailable, any Windows program trying to access the share will appear to stop responding, or "hang," if the mount type is hard.

-o anon

Mounts as an anonymous user.

-o nolock

Disables locking (default is enabled).

-o casesensitive

Forces file lookups on the server to be case sensitive.

-o fileaccess=<mode>

Specifies the default permission mode of new files created on the NFS share. Specify mode as a three-digit number in the form ogw, where o, g, and w are each a digit representing the access granted the file's owner, group, and the world, respectively. The digits must be in the range 0-7 with the following meaning:

  • 0: No access

  • 1: x (execute access)

  • 2: w (write access)

  • 3: wx

  • 4: r (read access)

  • 5: rx

  • 6: rw

  • 7: rwx

-o lang={euc-jp|euc-tw|euc-kr|shift-jis|big5|ksc5601|gb2312-80|ansi}

Specifies the default encoding used for file and directory names and, if used, must be set to one of the following:

  • ansi

  • big5 (Chinese)

  • euc-jp (Japanese)

  • euc-kr (Korean)

  • euc-tw (Chinese)

  • gb2312-80 (Simplified Chinese)

  • ksc5601 (Korean)

  • shift-jis (Japanese)

If this option is set to ansi on systems configured for non-English locales, the encoding scheme is set to the default encoding scheme for the locale. The following are the default encoding schemes for the indicated locales:

  • Japanese: SHIFT-JIS

  • Korean: KS_C_5601-1987

  • Simplified Chinese: GB2312-80

  • Traditional Chinese: BIG5


Specifies the user name to use for mounting the share. If username is not preceded by a backslash (\), it is treated as a UNIX user name.


The password to use for mounting the share. If you use an asterisk (*), you will be prompted for the password.


If you make a persistent connection with mount, you must use Umount to delete the connection. Neither the net use command nor Microsoft Windows Explorer will delete these connections.
