FreeFileSyncSoftware introduction
FreeFileSync The first is the file synchronization function, which can perform one-way or two-way synchronization between two specified folders. Click the green gear icon in the upper right corner of the program window to set relevant parameters; during this period, you can also customize the files that need to be filtered. There are two filtering methods: "Include" and "Exception" to define the types of files that need to be filtered. This depends on your personal needs.
In addition, it is a function to compare files in different folders to see if they are the same. However, this function is more suitable for use before synchronization. The comparison results will be directly displayed in the list for easy viewing, so that you can clearly know whether synchronization is needed and save system resources.
