I want know how to use folder in playlist

That mean I want use interface like window

Folder A

- aaa

Folder B

- bbb

Folder C

- ccc

Files appear when I click a folder

but heresphere's playlist is ignore folder

I only can see file like this

aaa

bbb

ccc

It is very uncomfortable.

Please let me know if I don't know how to use it.

I put all the files in one folder and divided them into detailed folders.

So I added only one folder and made a playlist, but I don't know if this is the problem. 

It would be very inconvenient if I had to add all the folders.

My folder directory is like this

Vr folder

 - Folder A

            - aaaa

 - Folder B

           - bbbbb

 - Folder C

          - ccccccc

Playlists only have videos. When you add a folder to a playlist, the player will scan all the videos in that folder (and its subfolders), and then add it to the playlist. If you want to browse your folders, you need to use the file explorer. The media library also will display the folders under "sources".
