How do I delete a folder on the very top level, a folder that I created when I did the set-up of the cloud? Alternatively, how do I rename it?
First, what device and operating system are you using?
If I want to delete music from my Horace share then I click on the Red X at the top. See image below.
Click on, tap or activate image to enlarge it.
If you want to delete a share you do that in the Dashboard. See all information and Help that is provided in the Dashboard.
To rename a folder select it then right click on it and choose rename.
