Answer 2

In an 8.3 file format, you have 3 locations that may be used by alphanumeric characters to create a 3 character long extension. Using 0-9 and A-Z, you come up with a possible total of 26 letters plus 10 numerical values that are interchangeable. As such, there are 36 possible characters for each of the 3 positions.
