Resync

Non-destructive local folder synchronizer.

Features

• Efficiently synchronizes big file trees between local disks without computing checksums.
• Processes the updated, changed, moved, removed and added files independently.
• Allows to include/exclude files by folder, name or path using wildcards.
• Stores replaced and removed files.

Limitations

• Symbolic links are not processed.
