The difference is that Windows to some degree were "file first" you go to "My Files" and from there pick a file, double click and the correct application opens. Especially Win95 pushed the "file as entry point"

That was the difference to DOS, where you'd start the program and load a file from within.

Nowadays we have circled back to phone and apps, where often you don't really deal with files anymore, but data stored in some service remote and there isn't even a save button anymore (and where it remains it is a legacy thing with a floppy icon, with the file as archaic as the floppy)
