I have spent hours trying to sync my "Documents" folders (as well as Pictures & Music) between my desktop and laptop computers. I have installed and uninstalled BitTorrent sync. Given up completely, then came back to it because at one time, before upgrades and new hard drives, it worked beautifully. I am sure it is simple and obvious, but not to me. The last time was when I shared "Documents" from my laptop, I entered the key on my desktop computer which prompted Snyc to require the destination file. Instead of the default, I entered the path to C:\Users\Michael\Documents. Instead of syncing with the desktop computer's Documents folder it created a new Documents subfolder (with strange .bte files). I think it is this "destination" piece that I am messing up every time but in everything I have read so far tis is not addressed in a way specific enoiugh for me to understand.
