A mirror of the FreeFileSync source code, an open-source folder comparison and synchronization tool that creates and manages backup copies of files. It transfers only the minimal data needed by detecting differences between source and target folders.
Use cases
- synchronize files between two folders
- back up important files incrementally
- mirror a directory to an external drive
- compare folder contents before copying
- schedule automated folder sync jobs
- sync files across Windows, macOS, and Linux
When to choose
- you need fast incremental folder sync that copies only changed data
- you want a cross-platform GUI backup and synchronization tool
- you need one-way mirroring or two-way synchronization with conflict handling
When to avoid
- you need cloud-native backup with versioned snapshots
- you require a permissive license for commercial use without purchasing the Business Edition
- you want to contribute code - this repo is a read-only mirror
