I downloaded several to learn different programming languages and I have them in a directory called "Courses" and each programming language has its own directory, for example, for Bash it would be Internal Memory > Download > Courses > Bash and so on with each programming language,

The problem I have is that many of those courses are divided in more than one playlist, for example, a Bash course has 20 directories and each directory is a category of the course (arguments, variables, strings) and inside the directory has its own videos that start numbered from 1 and this is a complete disaster using the VLC Playlists function because as each directory has its own numbered video that starts from 1, VLC orders all the videos that start with a 1 in the playlist, even if they are from different categories, so mixing for example video 1 from the arguments category with video 1 from the functions category.

Is there any video player that allows me to do the same function of VLC but that allows me to separate the playlist for each directory within the base directory?
