I wish to move wrongly placed sub folders out of main folders and reinstate them as main folders. The official DB advice is to open Files and "hover" over the selected file, look for the "three dots" and move it. But it is not clear what "hover" means. And although three dots appear in certain locations, they in practice do not allow me or help me to move stuff to my preferred locations but make daft suggestions. A false click can make a bad move but it is hard to make a good click to make a good move. Manual movement of files or folders usually produces the error massage that the file or foldr cannot be moved.
