Subst
Purpose:
Substitutes a path with a drive letter.
Syntax:
subst [drive: )(path ](/d)
Comments:
The subst command lets you associate a path with a drive letter.
This
drive letter then represents a virtual drive because you can
use the drive letter in commands as if it represented an actual
drive.
When MS·DOS finds a command that uses a virtual drive, it replaces
the drive letter with the path.
If you type the subst command by itself, MS· DOS displays the
names of the virtual drives in effect.
To delete a virtual drive you use the /d switch.
Example:
The following command creates a virtual drive, Z, for the path-
name b: \ user \ betty \forms:
5ub5t Z:b:\u5er\betty\form5
Now, instead of typing the full pathname, you can get to this
directory by simply typing the name of the virtual drive:
z:
