I am a DJ and a sound designer, so I have thousands of small audio clips stored in folders under my /Music directory. These are all less than 1-second clips of drums hits and samples, etc.

When I open MIXO on my Mac, it seems to automatically includes all 500,000+ tracks from my /Music directory.

I have manually deleted all of the them (except for the music I want to keep) but when I reopen all the files are back again. Is there a way to black-list, exclude or ignore directories so that I do not clog my queue with hundreds of thousands of unnecessary files
