FreeFileSync is a powerful open-source folder comparison and synchronization tool. It’s engineered for the highest performance and superior usability, featuring a streamlined interface that is neither restricted nor overloaded. This makes it an ideal high-performance file synchronization software.
FreeFileSync excels at synchronizing files between two folders or drives. You can either mirror two folders, creating an exact copy of the source folder, or perform two-way synchronization, which intelligently copies new or updated files in both directions, making it highly versatile, high-performance file synchronization software.
FreeFileSync offers robust support for Unicode and Networks, ensuring seamless operation across various environments. Its integrated synchronization database intelligently propagates deleted files and reliably detects conflicts. This high-performance file synchronization software supports multiple folder pairs, each with its own configuration, giving users maximum control and flexibility.
FreeFileSync provides full compatibility with advanced Windows file system structures, including Symbolic Links and Junction Points. Additionally, the program includes a specialized Update mode that efficiently copies only new or modified files, further enhancing its capabilities as a leading high-performance file synchronization software.
