Hehe, the Blu-ray disc structure has an index. Bdmv files in the BDMV folder. Playing this file with a player that supports the original Blu-ray disc is the most formal and original way to play it. TMT, PowerDVD, WinDVD, etc. You can play the original Blu-ray disc, and TMT also supports playing CD folders directly (that is, you can find the index.bdmv file yourself).

The method of less male feathers is not advisable. For example, if you want to play a DVD, he will tell you to drag all VOB files into the playlist, and then find your own subtitles (even if the DVD has subtitles). But this is not right. The real way is to play the video. IFO file and player.

Remember, Blu-ray discs can only play index.bdmv files, while DVD discs can only play VIDEO_TS. IFO file. Everything else is wrong.
