Need the same files in two folders or on two drives? SyncToy creates folder pairs and lets you choose how changes should pass between them, then preview the planned work before running a sync.
Which sync behavior fits the pair?
Each pair has a left and right folder. SyncToy’s three actions determine how files move between them:
- Synchronize copies additions and updates in both directions, and carries changes such as renames and deletions across the pair.
- Echo sends additions, updates, renames, and deletions from the left folder to the right.
- Contribute sends additions, updates, and renames from left to right, without propagating deletions.
Preview before syncing
After choosing folders and an action, preview the proposed changes to see which files SyncToy plans to copy, rename, or delete. This gives you a chance to inspect the effect of the selected direction and action before making changes to the folders.
Repeat runs for backup and shared files
A folder pair can connect folders on a computer, another drive, or removable storage. Run it when you want to bring the pair up to date; recurring runs can also be scheduled through Windows Task Scheduler. These workflows suit tasks such as keeping a working folder aligned with a drive copy or maintaining a second copy of selected files.
