Deleting all old upgrades

Forgive the dumb question but I’d rather be safe than sorry.

When doing an upgrade, on the step where you upload the zip file, there is a long list of old upgrade files going back to much older versions (I have about a dozen). Question, is it safe to delete these files via the upgrade wizard? Do they server any purpose? I suspect the answer is no. Could someone confirm?

Much thanks.


Yes you can delete. This has no effect
