i judge a search tool by wether it can find secret folders such as dllcache most cant find it no matter what. ontrac's file finder is the best and finds more than what copernick does although i like copernick, file finder doesnt require an install and none of the extra clutter, just a small simple file but finds everything including dllcache
forgot to mention its included with powerdesk5 usually but is a seperate program by itself, you should beable to find it standalone somewhere.
