FreeFileSync

FreeFileSync offers a streamlined approach to folder comparison and synchronization. This cross-platform, open-source tool analyzes the contents of your source and target folders to detect exactly what has been added, changed, or deleted. By transferring only these minimal changes, it completes sync tasks quickly and conserves disk space. It's the perfect utility for users who need to maintain identical folder structures for backup, mirroring, or simple file organization purposes.
