 The script works but as of now there is no way to recompress the files and very few of the models have been opened because LucasArts seems to have invented or modified an already non standard format. 
 This thread is to post your ideas, results and projects concerning the decompressing of TFU 
 Keep in my this only decompresses .lp files and the QuickBMS has no user interface to speak of, so this process is not for a novice computer user. 
 Good luck! 
 Edit: the link to QuickBSM is categorized as Malware by some website advisers, its clean.
