Backup on Android and restore on Win 10 still has some issues.
- the message when restore did not work should be more specific: which files / paths did not work, which replacements have been applied
  (see screenshot Restore_completed_with_errors.png)
- restore did not work for certain songs, I'm not sure if this was caused by special characters in song titles, only 14 out of 1000 were reported as errors (see screenshots MissingFiles1.png, MissingFiles2.png)
- songs from fakebooks are located strangely after restoring an Android backup into MSP on Win 10 (see Folders+Files.png)
  Restore creates a folder for every song where it stores the respective file. It should first detect if "Create Subdirectories For Songs" was set in the backup before restoring files and then act accordingly. In case of many different songs taken out of one fakebook it seems to create a folder for the first song found and stores several fakebook files into that folder named like the song instead of "the other way round" - folders per fakebook and then let the songs refer to that file (see Folders+Files.png)

With handling restore like this, restoring an Android backup on Win10 seems to work. When creating a backup of the result on Win10 and restoring it on Android, the file and folder structure is completely lost and can not be re-constructed.
