Folders may be renamed by connecting to the Aurender's internal storage from a Mac over your Local Area Network (LAN). Please see the link below for instructions on connecting to the Aurender from your Mac:
Once the Aurender is accessible from your Mac, simply navigate to the folder you wish to rename and Right-click (or Control-click) the folder name and select "Rename" (1). Enter the new folder name and the folder will change (2).
Placing brackets around a folder name, i.e. [Classical], will prioritize the first five folders beneath the root folder (Music1 or Music2) so that they appear in the second row of filter buttons on Conductor.
