Twenty-three, subst connects a drive to a subdirectdirect

For example, if the request for the A:\l1\l2 subdirecte is mapped to an S disk, enter it

subst s: a:\l1\l2

This uses commands such as dir s:?to display the contents of the subdirecte of a:\l1\l2, as in the case of the other copy del

You can cancel this mapping with subst s: d.

You can use subst to display various join situations

Note:? You can use Subst a: c:a to build a reading and writing disk for A. F or some installation software

You must use an A disk to install it, and you can copy all the software you want to install to C:a child first

In the directory, then enter subst a: c:a, then go to A:, you can install the software.
