FreeFileSync 3.6


FreeFileSync syncronizes files and folders using a simple to use interface.


It can do the following: compare files by their content or by file size and date, synchronize files and subfolders, process multiple pairs of folders at once, load/save folder comparison sessions, create batch jobs that can be run from the command line, and can can handle cloned files (i.e. symbolic links or junctures). It also offers UniCode and Network support. There is also a portable (no-install) version.
