We have created 3 MAP drive of our 3 different MFP and NAS in our PC. Z:/ ,X:/ and Y:/
File system property of Z:/ is NTFS and for X:/ is VFS and for Y:/ is FAT.
we are able to Monitor for NTFS file system MAP drive(Z:/) through our WPF Application .
But for VFS(X:/) or FAT(Y:) MFP's File system property
Directory.GetAccessControl(Path) API method throw below system exception. And unbale to Monitor the MAP drive
Method failed with unexpected error code 50.
we did not get any clue why this system exception coming for X:/ and Y:/ .and why no any exception came for Z:/ and other NTFS local MAP drive .

I created a new volume and set the File System to FAT, but unfortunately, I didn't encounter your problem,Directory.GetAccessControl(Path)works fine.
Does this happen in Windows? Could you please provide a more complete code and error message for us to test? -

When we Pass our MFP map drive as a String path X:/ and Y:/ it throw system exception . but it working fine for other local MAP drive and our NAS map drive because the file system property of our NAS and Local MAP drive is NTFS. It also Work For FAT32 but only problem with VFS and FAT.

I can't reproduce this error because I don't have an MFP, but for local volumes, there is no difference between NTFS and FAT, and neither will encounter this error.
For error code 50, it means that the request is not supported.
System Error Codes (0-499)
What brand of MFP is this, is it possible to set its file system to NTFS?
To be honest, this is a bit beyond the scope of programming, so the help I can provide is extremely limited.
Maybe you can consult the manufacturer to see if they can provide some help.
