* How to run it: Usage: ddff.exe... For example: ddff.exe C:\ D:\ E:\ Some information (partial and full filehashes) are stored into NTFS streams, so the next scanning will be much faster. * Comparison to other duplicate finding utilities: + Very fast + Comparing only file contents, 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" + Absence of unnecessary switches. - Win32 only - Command-line only
