Lacks sophistication


While the graphical interface is excellent and well-thought-out, I felt that the application did not perform as expected. This of course could simply be my experience as I do not know of the experience others have had.
My task was to sort my hard drive of 270 GB, most of which were images and remove all the duplicates. In many cases, I had located 3, 4,or even 7 duplicates. My desired outcome was to use this app to find these duplicates and at my request, reduce all of them to one, throwing out anything extraneous. Unfortunately, the application only located the files, albeit, in an simple format, but in most cases, I was forced to go through them item-by-item (yes the entire 270 GB) to ensure that the appropriate files were selected…. 1 day later, I’m done. Perhaps a revision on the algorithm is in order. Great idea and introductory function! But we need some better functionality on this one. I would have paid slightly more ($5?) for an app that worked to save me time and effort.

So so

Interface could be better. Hard to actually compare duplicate folders/files—paths are truncated. You can open the actual folder, but still kind of a hassle. Fonts used for paths/interface appear with too little letter spacing and are hard to read.

Great Value - Works


Does everything you expect. File scanning is fast and efficient.
