Thanks, but my case is different. Let's say I have a sync folder called "Sync Folder". In there is a folder called "Pictures". In the Pictures folder is a bunch of files, say A.jpg thru Z.jpg. At this point everything has been synced. Now I make a new folder called "Pictures 2", and I move A.jpg thru J.jpg into it. Everything has stayed within my synced folder, I've only done some rearranging. But I think things get deleted and re-uploaded rather than moved. And the same goes if I just rename a file without otherwise changing it or moving it at all. BTSync doesn't seem to follow those operations. I could easily test this myself but I only have one computer and my users are in different time zones and very difficult to coordinate tests with.
