I have lots of pictures only beeing named by date and time (yyyymmdd-hhmmss.jpg).
To make finding thing easier I concider renaming them (yyyymmdd-hhmmss Description.jpg).
Will FreeFileSync understand this and just rename the file on the "other end"?
Or will it delete the file and copy the file again (we are talking thousands of files)?
