ARCHIVED: In DOS, how do I rename drives and assign drive names to subdirectories?

You can rename subdirectories as drives and/or assign other names to drives using the SUBST command. In the following examples, E: is used as an example of a new drive substitution.

To turn c:\dos into e: , enter: SUBST E: C:\DOS If you enter SUBST by itself, a list of the current substitutions will display, as illustrated below: E: => C:\DOS To cancel a substitution, enter: SUBST E: /d Note: Do not use backup, restore, format, diskcopy, or diskcomp while a substitution is in effect.

Warning: SUBST may conflict with Novell drive mappings. After logging into your LAN, enter MAP to find out which drive letters are in use. Avoid using these drives with the SUBST command.
