A USB flash drive can host "Tourist Trophy" replay/ghost files downloaded from either the official game website or elsewhere online, and can be used to exchange files with another USB device. Once the files are in the flash drive, the user can upload them from within the game in order to compete with a ghost ("Time Attack") or to watch a replay ("Replay Theater"). Each file can be used as a Replay or as a Ghost. Formatting the USB device from Theater Mode will create the "PDI" folder, allowing "Tourist Trophy" to store, upload and download files generated under the name "replay.dat". Standard third-party USB devices are also compatible with such files.
