Two-Way File Sync in Windows 11, 10, 8, 7 | Best Practices


What Is Two-Way Sync?

Before understanding two-way synchronization, it’s necessary to know the one-way synchronization.

One-way sync is a sync mode that syncs items you specified from the source directory to the destination directory. Any changes in your source location, like creation, deletion, and modification, will be synced to the destination.

Two-way sync (also called bidirectional sync), is another sync mode that syncs items between the source and the destination location. Any changes in the source path will be synced to the destination; any changes in the destination path will be synced to the source as well. Two-way sync mode keeps the two folders exactly the same.
