Hi Helen, Thanks for the answer. Unfortunately, as I know it's not possible to select a folder from local phone storage to sync (in WP8 it is only possible to sync folder from PC/NAS running btsync). IMHO path you presented won't work. On the other hand, I can download document from btsync container to local storage (e.g. opening file, editing, and saving in local s.), but current release of btsync doesn't allow user to add this file back to btsync container. Or maybe I'm doing sth wrong ;> If the second one way works, the first one wouldn't be necessary .
