After defragging my mother-in-laws pc a couple of times today i have diascovered that there is a large file that did not defrag. it is:

dicuments and settings\all users\ application data\microsoft\dr watson\drwtsn32.log

and it's running in at a whopping 2.35GB with 19,782 fragments, is it safe to manually delete this file?

Hey there,

Sure, you can delete this log...it only contains accumulated information about your system crashes etc. If/when your PC crashes again, the log will be self-generated fresh.

WOW , a 2.35 gb log file?? :shocked: I would delete it.. mine is a couple of mb..

Just in case replace it with a log with the same name and containing:

thanks for the advice guys, it has been removed and the system performance has been drastically improved

Glad to hear it mate.
