mountvol Drive**:** /s


[ Drive : ] Path   : Specifies the existing NTFS directory folder where the mount point will reside.

VolumeName   : Specifies the volume name that is the target of the mount point. The volume name is of the form \\?\Volume{GUID}\, where {GUID} is a globally unique identifier (GUID) (for example, \\?\Volume\{2eca078d-5cbc-43d3-aff8-7e8511f60d0e}\).

/d   : Removes the volume mount point from the specified folder.

/L   : Lists the mounted volume name for the specified folder.

/s   : Itanium-based computers only. Mounts the EFI System Partition on the specified drive.

/?   : Displays help at the command prompt.


  • If you are running out of drive letters to use, mount your local volumes with no drive letters.

  • If you need to expand your volume space without reformatting or replacing a hard drive, you can add a mount path to another volume.

  • The benefit is that if you use one volume with several mount paths, you can access all local volumes using a single drive letter (such as C:). You need not remember which volume corresponds to which drive letter, although you can mount local volumes and still have them assigned to drive letters.
