Also it's worth mentioning, if I still had my files from my 486 PC (I don't), could I even access them? Mostly, not, or not without an emulator and fifty floppy disks of some ancient app I binned in the 1990s. And a floppy disk drive. And an adaptor cable. Files rot, unless they are intentionally low rot by design. Most weren't.
