FreeFileSync

FreeFileSync is a powerful folder comparison and synchronization tool used for backing up and managing files. It supports two-way sync, mirroring, real-time sync (with RealTimeSync), filters, batch jobs, and versioning.

It is especially useful when:

  • You need to keep two folders in sync — locally or across drives
  • You want to mirror files to an external disk or NAS
  • You prefer a graphical interface with automation capabilities
  • You need cross-platform compatibility (Windows, Linux, macOS)

FreeFileSync is available for all major operating systems. The builds offered here are full-featured and include RealTimeSync.
