Ratings and Reviews

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.

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...

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?!
