I have put more features in to this thing than I thought I would when it started, and have been tooling around with it for months years, on and off. Features include: Handles large files with no GUI stuttering/pausing Will check if a file needs to be copied by If Exist, size, date, and MD5 check Optional file Create, Access, and Modify timestamp preservation Optional Source file deletion after sync Optional deletion of Destination files no longer present in Source (ala Robocopy /MIR) Per
