Does what it claims and does it well.

If you have a large file library (and boy do I ever..) patience is a must when scanning. I start mine up before I go to bed and its definitely done by morning. I tend to not scan an entire drive at one time, preferring to focus on invidiual folders.. makes the scan time less painful and the number of files easier to work with. I love the clean interface and the animations are amusing without being overdone. Gotta love programmers with a sense of humor :) Anyway, RTFM and you shouldn’t have any problems using it. Its not rocket science, people. It guides you along the way.. I don’t think an app could be any easier to use.

Time Saver!

When it comes to finding duplicates, this app made my day. I was dealing with a photo consolidation project, where I had photos strewn across multiple computers, Dropbox, iCloud, and more. I was able to point this app to each of the sources and delete all the duplicates. I was leary at first, so I made sure I had backups, but its consistency quickly made me realize I could trust it. Mine is just one use in a thousand, but I am really glad this tool exists for this purpose and I will be using it more often when dealing with all file types from now on.

Love it except….

Perhaps it is just me or how my mac is set up, but it has block features on so many things, that is protected so it cannot scan it. That is a bummer because this is greatly designed and scans fast and easy. If anyone knows of how to enable it to scan the forbidden sections with being safe to enable it to do so, please tell me how! I love this and would love to scan EVERYTHING! I would still download it. It will be useful for everyone. I just can’t use it in all files or all areas of my photos in which I need to the most.

Other than that... this is a ten star app!
