When ripping Blu-rays, the folder structure includes an index.bdmv file. Tools like MakeMKV use this file to understand the disc's content and organize the various video streams into separate MKV files.
Many media players (like VLC) display the "Title" tag embedded inside the MKV metadata rather than the actual filename. This often happens with files ripped from DVDs/Blu-rays, where the internal title might just say "Title 01" or the name of the disc.
