? comparing folder contents to sync - for home use - not source code

[xmlguy]

over the years i have accumulated a lot of Hard drives, kids siblings etc - this question is about general daily contnet not source code



I repeatedly copied some of them over... 
Now I need to sort this stuff out.

I have a 8 to 12 GB of data to sort out. Contents as emails, pictures, software ISO etc.

Is there a tool for comparing folder contents and tell me if the files are identical and sort all the unique files into one folder.

Best I've any experience with is shareware called DoubleKiller Pro. DC member BrotherS gave it two thumbs up in a mini-review here. Another option is LookDisk. This is a tool that combines text and file search with duplicate file detection. The link is for the last freeware version (2.5). The latest version is shareware and is available from Iconico. I've got the latest version installed but have not really used it for this purpose - already had the DoubleKiller licence!

Oops. Didn't read the key last line in your post:

I don't *think* either LookDisk or DoubleKiller Pro will do this... Be a killer feature, though! Keep your eyes on XYplorer, come to think of it (note the link is to the road map for the developmental future - finding dupes is pretty far down the list...). The developer is working on adding a duplicate file finding feature to it and, as it is a file manager that is built on a search engine, he might be willing to consider adding this capability in.

If the files are different, but have the same names, do you want them automatically re-named, or overwritten?
