Allows you to substitute a folder on your computer for another drive letter.

Associates a path with a drive letter.

SUBST [drive1: [drive2:]path]
SUBST drive1: /D

  drive1:        Specifies a virtual drive to which you want to assign a path.
  [drive2:]path  Specifies a physical drive and path you want to assign to
                 a virtual drive.
  /D             Deletes a substituted (virtual) drive.

Type SUBST with no parameters to display a list of current virtual drives.

EXAMPLES

SUBST a: .   Sets the directory you are in and subdirectories thereafter into the A: drive. So if you were to type A: after doing this command you would see everything in the directory that you typed this command in.

If you were to reboot your computer this will clear the SUBST command and put your drives back to original letters (unless command placed into the autoexec.bat).

You cannot subst network drives.
