Hey Adam!
Yes, it’s actually really easy, but tricky to figure out!
In your Settings (F10), select the File tab.
Under “Browse extra search folders”, you’ll see a bunch of Folder Paths. Double-click on one to edit it.. just delete text and hit enter.
You have to close the Settings Pop-Up for the FL Studio Browser to be updated with your new folder layout.
I actually have a free FL Studio Tutorial about Deleting Empty Folders in FL Studio’s Browser!
