  MTP indeed has its limitations, after all, it stands for Media
*Transfer* Protocol, not access protocol.

  However, it's quite possible to overcome such limitations and treat
such a file-tree as a 'drive'.

  For example 'ftpuse' [1] - a 'net use' look-alike - can make an FTP
server look like a Network Drive).

  FTP - File *Transfer* Protocol - has similar limitations as MTP, yet
'ftpuse' manages to make it look like a drive (with a drive letter).

  So it *can* be done, but hasn't be done (by Microsoft).

  FYI, I used 'ftpuse' in the old days for backup of (parts of) my
Android devices.

  N.B. 'ftpuse' is not a solution the the OP's (Alan Peeling) needs
(making complete backup of his phone), because a FTP server on Android
can also not access the app-private data areas (/Android/data, etc.).
