Therein lies one problem with the lookup table approach - I have seen 
several packages using long "Linux" filenames in TGZ files, which use 
filenames that have large similar portions, viz.

open_file.c
open_file.h
open_file_mic.c
open_file_mic.h
...

(just a made up example)
I'm sure you get the idea, and you see the problem - either we will 
need user intervention to take care of this, as in "enter new file 
name: " or we will need to arbitrarily assign filenames that 
guarantee uniqueness and the FS may not decide that a file is 
"unimportant".  Also, what if:
c:\thisone\level.help\open_file.help
c:\thisone\level.help.source\open_file.help.txi
?? ;-)
