FreeFileSync is an open source file/folder comparison and synchronization freeware with visual, clear and friendly UI, specially designed for assisting data backup on Windows, Linux and Mac platforms.

In general, FreeFileSync has two major features. The first one is file synchronization function, which can perform one-way or two-way synchronization between the specified two folders. It allows us to filter files, choose "include" or "exclude" filter type, and define the file types need to filter. All depends on personal needs.

Another important feature is to compare files in different folders. But this function is more suitable to use before synchronization. The results of comparison will be directly shown in the list, convenient to check. As a consequence, you will be clear about whether some files need for synchronization or not, so as to save time and system resource.
