not that
@Erel needs my help, but you should do what he says.
this is how you do it:
https://www.b4x.com/android/forum/threads/organizing-dirassets.26789/#post-154946
you can have sub-folders and sub-folders of sub-folders with dirassets. no problem. plus
you can access the files by name. with res/raw, you need the resource id.
per google documentation:
"... if you need access to original file names and file hierarchy, you might consider saving
some resources in the assets/ directory (instead of res/raw/). Files in assets/ aren't given
a resource ID, so you can read them only using AssetManager."
