Go For IT..

create yourself a Windows 95 boot floppy...
...nah just messing, if its just unwanted files why not, erm, delete them ??

If you seriously want to do this, make sure you have a Good CD, Boot floppy with support for your CD-Rom.

after booting up from floppy

D: <return>
DIR <return>

if you can access the CD your laughing. If not dont go on.

a:
format C: /s

bye bye HD..go to the d drive and run setup.

come back in a few days when finished.
