GlBasic does auto copy files, if its not exists in the Media folders when you compile to various platform.
Howover there is some chases I do NOT want to do that, because I example not to want to ad a game for a competing platform, because it not exists on Android, but for iOS only (and I also might do some other small details, that might only shown on iOS or Android and no reason to include both graphics.
Is its possible to let GlBasic NOT copy a contain folder in the Media folder (or the other way via files panel), so I want to do sync my self (which here I do use a external one, so I have more control)? Or should I use a shoebox? its could even been folder with the platform name (etc iOS under Media for iOS only etc).
It only copies files there, that are in the Media directory. And it only copies if you compile for that platform. If you want a file only in one platform, just copy it there - not in your project.app/Media directory.
The copy is really needed because of the packing.
