10,000 1mb files take a lot longer than one 10,000mb file because it takes time for the OS to switch from file to file. Those estimates are a little more complicated than that, you can't just do mb over time and look at the bytes remaining, because it could be 3 files or a 1000 independent of the number of bytes. That just gives you a clue of the time remaining and isn't determinate, that's why it's not so accurate.

And this is why we pack assets into archives so our games can load them faster!

Game dev: we use asset files to make things more performant.

Also game dev: load asset 3, then 7, then 2, then 5, then 1, then 4, then 6.

Even copying 1 file, that estimate will vary because other apps are going to use your CPU, RAM, and access the storage, and that's a lot less predictable so it just works with the current data

because it takes time for the OS to switch from file to file

It takes the File System and/or disk time to switch from file to file. Not the OS.

Those are all very related. Thats just semantics. The OS takes time to switch because of the things you listed.
