Ha! But that's for another thread's discussion.
This structure holds for Rainbow Six 3, R63 BA, and Splinter Cell - Chaos Theory.
One of the umd files (lipsyncxbox.umd) for SCCT has 10200 files in it! They are .bin files and judging from the name are likely compressed sound files of the characters' voices.
I hope you found this useful.
