What is the value of playerr.mp3Dir?

Great greetings Erel, I've known b4 for two years, and I've been following your help on the forum... it's finally my turn

I use 2 voids, 'LPastas' to list the folders, which I list normally and 'LArqs' to list the files, before it worked normally but now it doesn't

LArqs use playerr.mp3dir to list files, but returns 0

The only folder that is directly accessible is XUI.DefaultFolder = File.DirInternal.

If you want to choose a file in a different folder then use ContentChooser.

No, dont need choose a file in a different folder... need just List a files

ContentChooser it wouldn't work for my project

Before it was listing the folders normally, but I changed a comma and it stopped, I don't know where I changed it, but it doesn't list anymore

I'm starting to think it's a bug in the platform, because I recompiled it using the backup .rar (when it worked) and it doesn't work either
