"You indicated that you "moved" My Documents to D:\ but still have a My Documents on C:\."

Moving My Documents.

In Win98

use TweakUI - you have to have downloaded and installed it - it wasn't a standard thing - dunno where you will find it now.

The My Computer Tab allows you to twiddle where things like My Documents will be seen by the system - Tweak UI allowed you to twiddle these things without using Registry Hacks.

I moved several things, including my Desktop to other drives.


"Disk Cleanup (it used to be called ChkDsk?) "

Sorry, 2 different things.
CHKDSK fixes any lost clusters, etc.
It SHOULD be run before attempting to run DEFRAG.


You can put the TEMP DIR on another drive by putting in the AUTOEXEC.BAT file

SET Path="X:\TEMP";%Path%
where X is the desired drive
otherwise it likes to live in C:\WIN\TEMP or thereabouts, somewhere you never think to look to clean it out. Many things leave heaps of crap there - they are SUPPOSED to be deleted, but often never are.
You can break very little by emptying it.
