Unable to Move folder

Nextcloud V11, running on ubunbtu

I have a large folder with pictures, about 45gb which i am trying to move into a subfolder. For some reason i am unable to do it.

When i move via the web interface, all i get is “unable to move pictures”

Any suggestions?

Check your logfiles. Or start and move smaller quantities.

I would try it with the desktop synchronisation client.
