Find duplicate files locally and remotely
This package helps to find duplicate files on local and remote filesystems. It is similar to the fdupes command-line utility but written in Emacs Lisp and should also work on every remote filesystem that TRAMP supports and where executable commands can be called remotely. The only external requirement is a checksum program like md5 or sha256sum that generates a hash value from the contents of a file used for comparison, because Emacs cannot do that in a performance-efficient way. dired-duplicates works by first searching files of the same size, then invoking the calculation of the checksum for these files, and presents the grouped results in a Dired buffer that the user can work with similarly to a regular Dired buffer.
