In case we want to sync a file or a folder that ends with one or more spaces (" "), the synchronization will fail with no clear explanation of what has happened.

Files/folders with trailing spaces should either be down-synced normally (if the OS supports such naming), or, a clear error should be displayed giving the user a chance to fix the naming on the server.

Another suggestion - make the server trim the name of any new uploads to prevent this from happening in the future. When trying to create such files/folders via the Web UI - this is not allowed by the server.
