You realize that you can copy files gl and from other providers like Google Drive, Dropbox etc from the files app on iOS just like you do on any GUI and you can also copy files from the iPhone by just plugging in a USB C mass storage device?
Never owned an iPhone, but I have familiarity. Here's Apple's instructions for "exporting" your photos from iPhone. Note: it does not say plug the iphone in and drag the photos from the "Photo" folder to your external device. It says this: > Export photos and videos to an external storage device > You can export photos and videos you took on your iPhone directly to an external drive, a memory card, or other storage d…
As far as why you can’t export your edited photos, is that iOS doesn’t actually exit your photos. It applies the edits from what I can tell as a separate “filter” that’s stored as metadata so you can undo your edits. How do you export your edits in a cross platform way? Would you rather have destructive edits? Maybe you would. But either way there are tradeoffs.
And files have a different data store than a photo.
You just plug any mass storage device into your iOS device and it shows up in the Files app and you copy and paste files like you would in the Finder or Explorer. In fact, in the Files app, if you have a third party storage service like Google Drive or Dropbox, they also show up as location in Files along with iCloud. Meaning you can copy directly from Google Drive to your mass storage device.
You can’t do that with any random “file explorer” on Android - ie a consolidated location for local storage, cloud storage from 3rd party providers, network connections, and mass storage.
