In the past i tried to rename a directory in my NextCloud. It was “12 SayIT PR” and a tried to rename it to “15 SayIT PR”. After that I had two directories. The new one (with my files) and a old one (only directories without files). But: I cannot delete the old one in the client and i cannot delete it in the web surface. I always get error messages (sync error in the client). In the web interface the error mesage is only “Fehler beim Löschen der Datei “12 SayIT PR”” (translated: "Error occured while deleting file “12 SayIT PR”).
renaming the directory fails also. Any idea, ho to delete this empty directory?
