Windows: Microsoft's SyncToy is a simple but effective tool for mirroring folders across hard-drive locations, networks or USB devices. With a 2.1 update, it's been retooled to run faster, back up configurations and handle errors much better.
We've previously featured SyncToy as a handy way to sync files between computers. It also ended up ranking among our readers' five favourite syncing tools. 2.1 isn't a huge update with new features, but it does utilise a new syncing framework and a few annoyance fixes that will win over those who dig this "toy":
- Better Performance: The speed of file copy operations is significantly increased across the board.
- Improved Robustness: Much more resilient to transient network and file system errors and better error reporting which pin-points which file the sync failed on in case there's a fatal error that stops the sync.
- Folder pair configuration backup: Folder pair configuration is automatically backed up under %localappdata%microsoftsynctoy2.0. User can replace SyncToyDirPairs.bin with the backup copy to resolve last saved configuration.
There are also a few bug fixes—notable among them is a fix for NAS syncing failure. SyncToy 2.1 is a free download for Windows systems, including 7, only.
