FreeFileSync is a file/folder comparison and synchronization tool.

It is optimized to allow the highest performance and usability without restricted or overloaded UI interfaces. You can quickly compare files (bytewise or by date) and synchronize them without limitations so an arbitrary number of files, subfolders, including empty folders, can be synchronized.

FreeFileSync features an easy-to-use UI that is geared for speed and huge sets of data. It is focused on usability; only the necessary functionality is provided, no overloaded menus or icon jungle to contend with. You have the option to select folders via drag & drop or by the last configuration, and your screen settings are saved automatically. You can fully maintain and load different configurations by drag n' drop, load-button or via the command line. FreeFileSync supports double-click to show files in explorer, copy & paste support to export file-lists as well as sorting of file-lists by name, size or date.

FreeFileSync also allows you to display statistical data like total filesizes, amount of bytes that will be transferred with your current settings. And when the need arises, you can delete any superfluous/temporary files directly on the main grid or right-click context menu. There are also progress indicators, status information and error reporting options.
