I've been using this for years. Excellent program. Works really well with Auslogics Duplicate File Finder and Total Commander to eliminate wasted space on your HDD.
One other option is to use a duplicate file finder type app. If you are swimming in duplicates then that may be the better option then manual.
I have tried, in the past, Auslogics Duplicate File Finder http://www.auslogics.com/en/software/duplicate-file-finder/
And
YADFR http://sourceforge.net/projects/yadfr/
I do not use them very much and in truth, usually manually sort and delete method has worked for me in the past. With the exception of Visipics app for jpgs. (I once got my backup pics mixed with my main working directory of pics and had to sort them all out, it was a real PITA had it about 1/3 done when I found visipics)
If you use the Duplicate File Deletion on any folder or directory, I HIGHLY advise you to make a backup of the directory first. Then do a cleaning and adjusting of it before you do it on the fly. It can save you from a bad situation where you delete songs that appear to be the same. Then once deleted you have to find them all over again. Or worse. Have to repurchase them from a store or something.
You could search for a duplicate finder. I know that CCleaner has one: https://www.piriform.com/docs/ccleaner/using-ccleaner/finding-duplicate-files - it's available for Mac.
That should make it a little bit easier.
This one seems to be a bit faster and has more features: http://www.auslogics.com/en/software/duplicate-file-finder/
And here is a comparison: http://www.techsupportalert.com/best-free-duplicate-file-remover.htm
I've got a bunch of files (something like 8 TB), and I want to organize them. The only problem is that there are a lot of duplicates (10 years of work files, pictures, gaming, etc. adds up quickly).
Is there any software that does a good job of detecting possible duplicate files on a local disk?
I want to clean up every duplicate possible, but it would simply take too long to look at every single file. Is there any software that highlights potential duplicates (and says how similar they are) so that I can look through just the potential duplicates and save a lot of time?
I found a couple things through Google (e.g. this one, this one, this one, etc.), but I don't know if they are any good (or trustworthy).
Does anyone have any suggestions?
Here's a couple I have used:
Auslogics has a better UI, but I prefer YADFR for its simplicity.
If you are cleaning up truly duplicate files (and not simply similar pics,) there are several good tools that'll help with this, like this one.
While I haven't used this program myself, I've heard Auslogics Duplicate File Finder works very well. It seems to have received good reviews as well, including by CNet.
