Aurender music servers come with default folder names on the internal storage. These folders can be renamed, and as a result custom folder names will appear on the second row of filters on the Conductor App.
Note that if you have more than five folders under the Root folder (Music1 or Music2), and you wish to designate specific folders to appear in the Conductor App's second row of Contents Browse filters, surrounding the folder name with brackets, i.e. "[Folder Name]", will designate the folder to appear in lieu of the other folders.
Folders within other folders may be renamed in the same fashion, with the exception that brackets only affect folders directly under the "Music1" or "Music2" root folder.
