I have a TrueNAS server at home and thought I could easily connect it to my phone (Pixel 7) as a network drive but was surprised to learn that Android doesn't have a built in feature for that.
iOS/iPadOS does have this to my surprise built in via the 'Files' app.
Or did I just not look hard enough in the Android settings? (I know there are 3rd party apps for this)
It's not built in, but I generally recommend Solid Explorer for that functionality: https://play.google.com/store/apps/details?id=pl.solidexplorer2&hl=en_US&gl=US
MiXplorer gang rise up!
Is that the official distribution link or a personal mirror?
This is official from MiXplorer XDA thread.
