My girlfriend had the craziest workflow. No laptop, only iPhone and iPad Pro. She had an external USB-C hard drive, she couldn't connect it to her iPhone but could to the iPad.
What she would do is airdrop photos from her iPhone to her iPad. Copy them from the gallery to the Files app. Move them in the files app to the hard drive. Then delete them from the gallery app, delete them from the Files app and the trash.
For some reason, deleting files in the Files app didn't free up space on the iPad. So she had to uninstall and reinstall the Files app to get the space back.
As a Linux user that grew up DOS, the whole thing just broke my mind. She was frustrated and I was frustrated I couldn't help her.
