Delete Documents folder

I have recently setup a new Nextcloud install. I mounted an external USB drive and changed the datadir location. So far so good. As I want to start from a clean set, I wanted to delete all standard data files (Nextcloud,mp4…). This works, but not for the Documents folder. I cannot seem to delete the Documents folder.

Is there a way to delete it?

Hmm should be possible. You checked data folder permissions? Also I watched sometimes a delay when deleting files /folders on web ui with slow system (raspberry pi) and external hard drive. You could try it with the sync client.
