Default Love It!
Absolutely love this mod! It works like a charm! No more 50-50 hunts (which I have done too numerous to count!) . Marvelous, thank you!

This is a pretty amazing program -- it's found duplicates that even ccleaner couldn't find. Thank you. It was especially useful in finding files that I had both as merge and separated. I always suspected there were some, but I was surprised at how many. Now my mods folder is much cleaner <3

I wonder if it could also be coded to find packages that had 'object defition' xml on them. A lot of cc has custome tuning and it is not appear at first that it is a 'mod.' Since those tend to break, it would be nice to be able to separate them. It would also be great if it could detect cc that is only recolors and is missing the mesh. Of course, the holy grail would be if this could sort cc by category as well. Ah.

thank you for your contributions to the community so much. I will surely be using this a lot!!

I don't believe this removes any files itself. It just shows you which ones conflict and then lets you decide what to do with them.

i love this mod, i know how to use the ‘search exact doubles’ part, but I am a little confused on what ‘search catalogue conflicts means’. I have 52 ‘conflicts’ but i’m not sure what that means or what to do? They’re all CAS items, and I didn’t think CAS items could conflict. Apologies is this isn’t clear, I’m just not sure what to do

Thank you so much for this! I have a ...probably weird question. I've just ported all my stuff over to a new computer and it looks like, in the process of using the program, it created my Documents folder twice, once under my Users/ file and once under a file it created to store things from my second hard drive on my old computer (since this computer doesn't have two separate drives). Is there any way I can scan the whole drive to try and figure out if one Mods folder has things the other doesn't?

It worked wonderfully when my mods folder was small, I tried again with 64 GB and it crashes half way through loading .
