A file name like "x310-b4r3-remux-rem-part13-rar" is more than just a random sequence of characters; it is a coded message that speaks to a specific standard of quality and a long-standing history of internet culture. It represents the intersection of technical precision, a desire for high-fidelity media, and the communal effort required to move massive amounts of data across the globe.

: This indicates the file is part of a "split archive." Because high-quality remuxes can exceed 50GB or 100GB, they are often broken into smaller RAR segments to make them easier to upload and download. If one part is corrupted, only that segment needs to be re-downloaded rather than the entire massive file. Digital Archaeology and Preservation

: This is a technical term indicating that the video and audio tracks have been "remuxed." Unlike a "rip," which compresses the video to save space, a remux takes the raw data directly from a Blu-ray or UHD disc and places it into a new container (like .MKV) without losing any quality.
