A command-line utility that mounts Network File System (NFS) network shares. When used without options or arguments, mount displays information about all mounted NFS file systems.


This utility is available only if Client for NFS is installed.


mount [-o <option>[...]] [-u:<username>] [-p:{<password> | *}] {\\<computername>\<sharename> | <computername>:/<sharename>} {<devicename> | *}


Parameter Description
-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 for your NFS share. By default, Windows uses a soft mount. Soft mounts time out more easily when there are connection issues; however, to reduce I/O disruption during NFS server reboots, we recommend using a hard mount.
-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, including:
  • 0: No access
  • 1: x (execute access)
  • 2: w (write access)
  • 3: wx (write and execute access)
  • 4: r (read access)
  • 5: rx (read and execute access)
  • 6: rw (read and write access)
  • 7: rwx (read, write, and execute access)
-o lang={euc-jp|euc-tw|euc-kr|shift-jis|Big5|Ksc5601|Gb2312-80|Ansi) Specifies the language encoding to configure on an NFS share. You can use only one language on the share. This value can include any of the following values:
  • euc-jp: Japanese
  • euc-tw: Chinese
  • euc-kr: Korean
  • shift-jis: Japanese
  • Big5: Chinese
  • Ksc5601: Korean
  • Gb2312-80: Simplified Chinese
  • Ansi: ANSI-encoded
-u:<username> Specifies the user name to use for mounting the share. If username isn't preceded by a backslash ( \ ), it's treated as a UNIX user name.
-p:<password> The password to use for mounting the share. If you use an asterisk (*), you'll be prompted for the password.
<computername> Specifies the name of the NFS server.
<sharename> Specifies the name of the file system.
<devicename> Specifies the drive letter and name of the device. If you use an asterisk (*) this value represents the first available driver letter.
