Definitions of SyncToy Actions

SyncToy can perform five actions on folder pairs.

• Synchronize: New and updated files are copied both ways. Renames and deletes on either side are repeated on the other.
• Echo: New and updated files are copied left to right. Renames and deletes on the left are repeated on the right.
• Subscribe: Updated files on the right are copied to the left if the file name already exists on the left.
• Contribute: New and updated files are copied left to right. Renames on the left are repeated on the right. No deletions.
• Combine: New and updated files are copied both ways. Nothing happens to renamed and deleted files.
