Yeah, great... simple?

Looks like I probably wasted $20. I simply want to FILTER out ONE folder on finder, "Users", as there are inherently a lot of duplicates there that need to be there as duplicates. Anyway, I tried EVERYTHING to get that "filter" option in preferences to exclude my "users" folder. Never worked, and one time I got some rdiculous results that made no sense. Went ot the support site, and could not find one article or tip or hint how to filter...

One of the best Duplicate tools

Over the course of a few years I tried all the duplicate file utilities I could find and eventually settled on DeCloner. This was after version 1.4 came out because it added multiple source options. 64-bit support probably helped too since I scan a lot of extensive archive hard drives with lots of files.

TidyUp is a good alternate, but I think it is cumbersome to set up and use if you need simple comparison of folders or drives. In a nutshell I found DeCloner the easiest to use.

Has a slight cosmetic redraw glitch in Lion, which I'm assuming will be fixed soon.

iphoto not obviously scannable

I bought this lieu of duplicate annihilator. I'm running it on my whole personal documents folder including all libraries but was not able to hit just the iphoto library like I really wanted. Where's the refund button on the APPLE App store?!
