Hi, are you sure you're using SyncBackFree? If so, it has no rename capability (from "This" to "That" - only from "THIS" to 'This", and so on, i.e. case difference only / names otherwise the same).
Only the commercial versions have full rename functionality, and only with SmartSync (which Free doesn't have) and yes, hashing is required to make 100% sure the files are the same content. So if you have an FTP server that doesn't support XCRC, it won't try, for example.
