DiskType

A quick inventory of the machine's drives: loop A through Z, call GetDriveType on each root, and print the numeric type for anything that is not DRIVE_NO_ROOT_DIR. The comment block at the bottom lists the constants - removable (2), fixed (3), remote (4), CD-ROM (5), RAM disk (6) - so you can extend it to friendly names in a line or two. Use it when your software needs to know what kind of storage it is about to touch.
