I am uninstalling btsync because of a fundamental issue in it's approach. I know others doing the same. From the source Windows machine, my android app syncs the subdirectory and file structure of a shared top-level directory flawlessly. However, and crucially, it does not sync the actual files, only a placeholder to create the structure. To sync the actual file, that is have the actual bytes on my device, I need to select that file in the Android app. I'm syncing say 200 files. I'm on a plane and no longer have WiFi. I need a file that I thought was sync'd but of course no, I have not previously selected it in the app and so I am seeing only the placeholder. So, no good. I have hunted through all options in both target and source devices, and nothing seems to force download of the actual files. Only the structure. Until this changes, I will not be using this application.
