Allow subfolder selection in Box

Feature description:

Only root folder selection is allowed, which requires that the music files be in that root folder. I think implementing folder navigation would make it easier to select the desired folder by eliminating folders that hinder the display.

Problem solved:

It would fix the display of music files that are in other folders within the root.

Brought benefits:

Greater clarity and avoids having to move files to the root folder
