Add directory clone detection

Sometime i keep 2 times the content of a CF card full of video or photos.

It will be great to have a detection of directory which all content are already present somewhere else.

Agreed -- this would be a massive convenience for deduplication efforts.

This would be great to have and a feature to merge very similar directories. Your tool is fantastic, fastest I have ever seen and I have tried most of them on mac, windows, linux.

For features you may want to look at Duplicate File Finder for Mac, that has the most usable set of features to combine and eliminate duplicates while doing a system cleanup. It is much slower than yours but it lets you clean things up very intuitively.

Totally agree. I also had duplicated folders which i had to figure on a file by file basis.

I guess after all files checks are completed, it would involve sorting by path and then a recursive comparison of hashes to determine which directories are duplicate.
