#!/usr/bin/perl -w # eXpanium converter tool V0.0.2 # # credits to a, tye, mkmcconn and all the other people at perlmonks.org who helped me +with regexps! # # This program should convert MP3 file names into the dos format (8.3) # and store the original names into a file. Once the names are conver +tet the # procedure can be reversed with said file. # # This program is used to make mp3 files burnable with mkisofs since t +his program # does not preserve the .mp3 extension on files that would have the sa +me filename when # shortened to 8.3 format. # # The program takes directories or filenames as parameters.
