I just ran into this trying to copy files off a current Android phone. Windows10 simply wouldn't select all files in the camera directory so I couldn't alt+enter to see the total size. Tried to copy all user-accessible directories, spent a while calculating size then failed with 'unspecified error'. I hope I can find a way to enable standard file access. I did manage to make a backup with ADB and then decrypt it with a java tool... and it only included two of the directories. Maybe my internal flash storage is corrupted?
