Working with/using files on NC-Server

Hi guys,

I wanted to set-up a Nextcloud-server on my HTPC running Manjaro KDE 21.0. I managed to do so using Docker.
So far so good and it works - the only thing I didn’t think about before is, that I’d like to use and work with the files on the HTPC too!
Is there a way to do so, or do I need a Client running on the same machine for this? But then the files would also be doubled… :see_no_evil:

Sorry for the stupid question and thanks in advance! :grin:

Edit: And if it’s not possible to solve my problem in Nextcloud, do you know a different approach? Thought of syncthing but missing out a lot of features…
