The subst command allows you to give a directory on a computer an actual
drive letter.

Let say I have a download directory deep into a directory.  I could use
subst G: C:\download\software\mp3\ to set a drive letter to that directory,
so I can just poing to that drive, instead of going through each directory.
It can give a drive letter a directory from any drive and directory.

I don't know why anyone would create a mirror of C like that, but at least
is an explaination of that command.

Subject: [PCSOFT] Autoexec line: subst L: C:\


Good evening ladies and gentlemen.

I ran across something I haven't seen b4 today.  A user's autoexec.bat file
had the following statement:

subst L: C:\

This statement in the autoexec.bat causes the C: drive to show up again as
an identical drive w/ drive letter L: (in MY COMPUTER - Windows 98).

What function does this serve?  Is it actually "mirroring" the drive?  If
so, where is the image?
Is this a security measure of some sort?
Does Windows "see" the L drive as another drive w/ a Windows installation
(I've seen this cause problems) or does it ignore it?


Thank you all in advance for your help.

(Thanx to those of you who responded to the [After Idle Period - lose OS]
thread as well.  Still waiting on word from the user re: status of
problem after disabling all power management features.)
