Hello, my latest code should allow you to perform the requested operations in "mixed mode".

@maxpat78 Just tested the following:

>>> from FATtools.Volume import *
>>> root = vopen('H:', 'r+b')
>>> root.listdir()
['MP3S', 'System Volume Information', 'C.mp3', 'B.mp3', 'A.mp3']
>>> root.sort()
(7, 121)
>>> root.listdir()
['A.mp3', 'B.mp3', 'C.mp3', 'MP3S', 'System Volume Information']
>>> vclose(root)

I was successfully able to access the drive by letter from within the OS after issuing the vclose, so it appears to function for me.

Thanks very much!
