I want to make a temporary drive

I want to make a temporary drive from the folder c:\tempdrive
I also want a batchfile (dels.bat) that will delete everything in the
temporary folder (drive).

I was reading this and I thought I would just ask directly. Since I
use this computer for P2P, I don't want to reboot it yet.

I issued the command "subst s: c:\tempdrive" from a command prompt and
it made the drive s:. I also put the instruction in autoexec.nt in
the root directory of c:

so autoexec.nt and dels.bat a

subst s: c:\tempdrive
s:
FOR /D %%p IN (s:\) DO rmdir "%%p" /s /q

This seems to work in the batch file. Is there any reason it won't
work in the autoexec.nt next time I reboot?

Also a Winrar question.......Can I add a command to the right click
menu to extract a rar file to s:\ ?
