FreeFileSync: Powerful, open-source file syncing & backup tool for Windows, macOS & Linux. Efficiently transfer essential data across devices and manage large collections.
FreeFileSync is a powerful and free folder comparison and synchronization tool designed to efficiently manage backups. It works by identifying the differences between source and target folders, transferring only the necessary data instead of performing full copies each time. Available for Windows, Linux (including an open-source version), and macOS, FreeFileSync significantly reduces bandwidth usage and processing time. Additionally, users can support the project through donations, with options corresponding to one year or five years of updates for amounts like €20 or €100 respectively.
