I compress my folders every couple of days. I defrag my HD's about once
a month. I have never had any problems after a defrag. Just for the
record.

Correct. About once a month here, as I donwload, install, uninstall,
delete etc a lot. Folder compression gives me over 1MB each time. I
like to have my files defragged, as I do notice a performance
slow-down (I have a speed of a mere 366MHz to search through 2GB of of
a not-too-fast Maxtor), and fragmented files are not as "neat" (from a
German perspective of having every "neat and clean" all the time - my
mother taught me well), and also, I think I read that file
reading/writing errors are more likely on fragmented files than on
those that are not.

On this I agree. Before defrag, reboot, and then close all apps that
run in the background (SETI@Home, anitivirus, firewall, of course any
internet connections, internat.exe, PGP Tray, etc) and let Defarg do
it's thing without interference. I guess if anybody has had problems
after a defrag, there might have been a program running in the
background, and hey, this is Windows, so don't believe that seperate
threads are always seperate threads.

It definitely is for C-Win98.

Then it must be SETI@Home. Crashes less often than windows. ;-)
