Finding files by owner in XP

Simple as that.

I have apparently used up all my alloted space on a shared drive but I’ve no clue where all the files are that I’ve created. I didn’t see an obvious way to find files belonging to me through the standard XP search utility. I found something called delbyowner on the net, but I was wondering if XP has an intrinsic way of doing this.

Disk Space Inspector claimes that it can scan directories and display file usage by owner but I’ve never used the program.
