Most folders are not directly accessible to your app.
Code to collect all files without freezing the app: https://www.b4x.com/android/forum/t...file-listfiles-to-update-ui.80260/post-508303

Thanks a lot for the tip Erel.
Do you have any example of how to do this in B4A?
I'm a beginner and I didn't find any post with an example in B4A.

I need a routine that finds all .mp3 files in the folder and all its subfolders.

Maybe try using that solution and then filter its results down by your criteria, eg: String.ToLowerCase.EndsWith(".extension")
