Duplicate Directories and Files Finder

Usage example: ddff.exe C:\ D:\ E:\ + Very fast + Comparing is based on file contents, so ignoring file name/attributes. + Comparing directories too. + Often, two directories contain, let's say, 4 equal files and 5th file is different. We handle it too and output these as "common files in directories" Some information (partial and full filehashes) are stored into NTFS streams, so the next scanning will be much faster.
