By using 6 bits per character and two high bits to terminate the filename, you could free up two bytes. 8*11 bits = 11 bytes vs. 6*11 bits + 2 high bits = 68 bits = 9 bytes Also, I don't think 4 characters is too limiting for users. If you consider input and display challenges not to mention RAM requirements, it may be more reasonable. I can see two-character initials plus two-character version number being "easy enough" to remember. But that's just me. :) -Lee
