Return values of function:

DRIVE_NO_ROOT_DIR 1: The root path is invalid; for example, there is no volume mounted at the specified path.

DRIVE_REMOVABLE 2: The drive has removable media; for example, a floppy drive, thumb drive, or flash card reader.

DRIVE_FIXED 3: The drive has fixed media; for example, a hard disk drive or flash drive.

DRIVE_REMOTE 4: The drive is a remote (network) drive.

DRIVE_CDROM 5: The drive is a CD-ROM drive.

DRIVE_RAMDISK 6: The drive is a RAM disk.
