Using a File index

[HS]

Hi all
I use to open files using recursive find.
Now I just did a ruby script to generate a list of all sources on some
given folder.
My problem now is to parse this file and use it to open the file I'm
looking for.

file1.c = c:\blabla\prj1\file1.c
file2.c = c:\blabla\prj2\file2.c
file3.c = c:\srcs\file3.c

Anyone could give me a hint?
Thanks in advance!
