I store a lot of terabytes of data in a NAS, so being able to copy files back and forth over my local network is important for me. I can do that pretty easily with file explorer apps on Android.
in my experience this is such an ambiguous statement with little effort of actually identifying "what" the desired needs, benefits, effects, etc. are. This is more "this is how I do it and don't want to change" than it is "these are the things I need"
I mean I have "terabytes of data" also.. most of us probably do. but how much of it is used primarily through cloud services, how much of it is effectively stagnant data (or essentially archived data), how much of it is fluid and constant use, etc.
if I were to look at my terabytes of data I can already say with certainty that it consists of:
hundreds (thousands?) of episodes of anime that are probably available on a dozen different streaming services
songs that are all on Spotify/Apple Music
movie rips that, likely at any given time, are largely represented on one or more streaming services.
a photo library of 19 years that has all been imported to iCloud Photos for the last two years
a home video library that similarly has all been imported into iCloud Photos for the last two years
once you remove all of those things.. and all of the downloads I've never cleaned up.. we are probably talking less than 500GB of files that I care about. and of the stuff I mentioned above, photos and home movies are the only thing taking up space on my iCloud storage. Which according to my phone right now is 350GB used for photos.
worst case scenario, I dump the files I care about onto my desktop or my documents folder and they get synced to iCloud Files available instantly to all of my devices and Macs.
