Singular helps you to find and remove duplicate files on your Mac. Drop files & folders on its window or its Dock icon, choose files with the open panel, it makes no difference: it finds duplicate files, shows you the results and lets you move them to the Trash in just a click of the mouse.

DISCLAIMER: this application moves duplicate files to the Trash. Use with caution.

This is perfect for cleaning up duplicate .eml files in Mail. You just drop the problem folders on it and don't have to worry about screwing up your whole Mail folder.

Going large folder by large folder, you can control and test and see what's been going on with Mail to inflate the size so much.

Really quick and with a very clear interface.

Brilliant little app.

This is completely useless unless you only want to scan very small folders. I initially tried scanning my entire hard drive and it crashed every time. I moved down to just my document folder and it ran for awhile and then even after being left all night long, didn't move any further. You can run small (MBs) folders but nothing large. This makes it completely useless for most people. Obviously I can see where my duplicate files are inside a small folder, it's the larger folders that are the problem!
I'll stick with Tidy Up! thanks.

Altough not available for purchase at the moment, (using the eval key)
I tried Singular today, and was great help solving my duplicate folder merge problems by eliminating duplicate files, so I could merge later with The Big Mean Folder Machine.

I wish this functionality was built in to TBMFM...

Was dissappointed w/ this app. Crashed several times and did not complete the scan in 'trial version'.

Developer offers 5 scans for free, then wants to be paid for his work. That seems fair, but the trial scanning did not complete, so was of no use to me.

While I don't mind paying for s/thing that works, this app simply crashed, and did not complete the task.

Not ready for prime time. Not at any price.Three hours ago I asked it to scan a medium sized hard drive. Nothing so far !

I suggest usingTIDYUP! or FILE BUDDY9 or my favorite - DupeGuru

It blows up if the file folder contains too many files.

Also, you are given the opportunity to delete n-1 files if n files are found. It might be nice to delete them all sometimes!

A nice feature would be to sort the files by pathname or by size.
