Me. I am basically trying to squeeze the desktop (PC) out of my phone, so there's a lot of "unnecessary" stuff.
For example, I am currently deciding whether to keep the 110GB of DVD ISO files which I can stream from my phone using VLC (on client side) which are served by nginx server from my phone (this way I still get all menus, just like with a physical DVD) or delete it and replace it with equally sized 110GB EN Wikipedia maxi .zim package, install kiwix-tools on Termux and set up nginx on Termux to serve as revese proxy to kiwix-serve so I could also host a mirror of the whole English Wikipedia, including (downscaled) images on my phone. I guess that sounds cooler than DVDs.
Or I should get a 512GB SD card and keep both.
I can't afford 1TB one.
But yeah, that's just one example. My 256GB SD card is about to pop while my video and music collection (The latter of which which is also served using Navidrome server in Termux 🙂. For videos I just use nginx with material fancyindex theme.) keeps growing.
I already have to keep some stuff on phone's internal storage.
Termux is godsent. Otherwise I'd absolutely have to get a PinePhone as I couldn't live with something as locked down as Android or even iOS without a nice terminal emulator.
Alternatively, I could benefit from pocket-sized passively cooled laptop.
I'm not deleting them. They're uploaded to the cloud at the time of creation. I also move them off my phone to my computer every 6 months or so - I do this just in case the upload to the cloud has ever silently failed. I deduplicate the images, so I don't have multiple versions of the same image with different file names.
For me it's not entirely about space. I rarely let the device get more than 2/3rds full. It's also about speed. If I want to pull a photo/video off my phone, it seems sluggish when there are thousandths of files in that one directory.
Ah, yea, I see. Makes sense. Minimizes your risk while also minimizing your effort to manage them.
Yea, I don't mind having photos on my phone, but managing them is far easier on a pc. So like you, mine all sync to my PC instantly, then when I feel like it I spend some time there cleaning them up (and the changes sync back).
Since the PC has Crashplan for backup, and a NAS it syncs too, I feel pretty comfortable my stuff is safe.
