Is there any free iOS video player that allows you to transfer and keep a folder hierarchy intact?

I'm using PlayerXtreme on my iPhone and it's keeping all level folder, you should try it !

I've only be using the free version so far, but it does the job (and you can get more feature by giving them an availiation on the Appstore)

On their website, they claim that :

• Files and Folders: Dont need to learn the app. It is almost like using Windows or Mac OSX.
• Library Organization: Organize all of your media-videos, photos, and music

The best file storage tool is the native tool, so just put your files in folders in the files app on ios13.

There’s no need for a player unless your videos use non-standard codec, and then start with VLC or a different player if you have such a large library that getting things encoded isn’t worth the time. Don’t even use VLC until you’re forced to. That being said, my Documents folder and dozens of music, video, pdf files all transfer perfectly from Mac to iCloud web interface to files on iPhone and iPad. VLC for iOS navigates this hierarchical storage perfectly so I’m guessing you are struggling to load your folders into VLC sandbox and not using the files app.

Putting video files (or any files) in a specific app sandbox is really fighting against the grain.
