  mountvol  Possible values for VolumeName along with current mount points are:         \?\Volume{efc6cef2-cd37-11d3-8139-806d6172696f}\         C:\         \?\Volume{886dfe07-d034-11d3-8142-0000b4a04774}\         E:\         \?\Volume{886dfe08-d034-11d3-8142-0000b4a04774}\         F:\         \?\Volume{886dfe09-d034-11d3-8142-0000b4a04774}\         G:\         \?\Volume{b5349550-d58e-11d3-8144-0000b4a04774}\         H:\         \?\Volume{0b77be43-ccff-11d3-b77a-806d6172696f}\         D:\         \?\Volume{0b77be42-ccff-11d3-b77a-806d6172696f}\         A:\ 

Notice that the Help file for mountvol is also printed (here omitted). Let's now create the empty directory C:\accounting and mount the H : drive to this directory. Working in the current directory, which is C: , do the following:

  md accounting  mountvol accounting \?\Volume{b5349550-d58e-11d3-8144-0000b4a04774} 

To see if it worked:

  dir accounting  Volume in drive C has no label. Volume Serial Number is D839-4CFA      Directory of C:\accounting     06/22/2000  01:40p                  46 doc1.txt 06/22/2000  01:44p                  30 doc2.txt 06/22/2000  02:12p  DIR  pub                2 File(s)             76 bytes                1 Dir(s)     497,959,936 bytes free 

This is the contents of the H: drive that's mounted to the empty folder C:\accounting .

Notes

• You can create mount points using Disk Management as well (see Disks in Chapter 4).

• Mount points can be used if you are running out of drive letters for local volumes and to expand the space on a volume without reformatting it or replacing the hard drive (just add a mount path to another volume). You can also use one volume with several mount paths to enable access to all your local volumes using a single drive letter.

• Don't delete a mount point using Windows Explorer or del /s because this removes the target directory and all its subdirectories. Use instead mountvol /d .
