Sharing files between apps and file management in general on iOS is atrocious.

I assumed this was a solved problem before Windows 98 (first desktop OS I used), but Apple cannot get this right 28 years later.

At least there is a Files app these days, and many iOS apps interoperate a little bit with “Files”.

Funnily enough, Windows 98 is the first OS I remember with a sharing menu (“Send To”, which is memorable to me because the official Russian localization of it was suggestive of an obscenity). It seemed so pointless back then.
