 A large number of backup files were made on Digital Linear Tape (DLT) which Disney/LucasArts had been able to recover for Double Fine, but the company had no drives to read the tapes.Former LucasArts sound engineer Jory Prum had managed to save a DLT drive and was able to extract all of the game's audio development data from the tapes.Schafer noted at the time of "Grim Fandango" original development, retention of code was not as rigorous as present-day standards, and in some cases, Schafer believes the only copies of some files were unintentionally taken by employees when they had left LucasArts.
