Files Manager will always copy the selected files to the B4A\Files folder of your project. This is fine for layout files but, if the app is intended for using a B4XPages app designed for cross-platform deployment, all files except layouts should be stored in the Shared Files folder.
It would be handy if File Manager had an option to also copy the file to the Shared Files folder.
