But that is exactly what I am saying. Everything I have on my phone has an app. Immich for photos for example.

Each app that stores things on my server already manages the data to get there.

So is there a need for a file server that works on my phone like this person is asking about?

I mean I do have SMB access from my phone as well, but I hardly need it since individual apps are already pushing and pulling data from my server.
