adding dir to foobar2000 lib snap (configuring files under WINE)

Hi, I can't figure this out and I guess I'm bad with internet searches... can't find any info on how to add a path to a snap. seems like what the snap sees is all emulated, but is it possible to place a shortcut in that sim dir? I tried to create one in the open file dialog box but didn't work. Also it doesn't see any contents of the Debian primary drive folders (sees the folders but not the contents).

Foobar2000 is a audio player and I just want to add a dir to its library so It can add the files to playlists.
