I'm definitely not handling exfat_uid as one of the supported directories. That's why it didn't work. I'll add that as another thing to look for.

Thanks,

This is a ridiculous situation.  You'd think that there would have been some agreement about naming such basic things as this!!  Something simple, like Disk 0 - root, Disk 1 - Internal storage, Disk 2 - External storage, would have made life so much easier for developers.  Google really did not think things through very well.
