The Windows portable installation has (or can have) the user settings folder (named '2.77' for instance, containing all the user preferences) next to all of it's files - which is perfect for me, since I can sync the whole installation via cloud drive.
But what is the proper update procedure in such a setup? A freshly downloaded portable installation already has a user settings folder, containing for instance the add-ons folder. So to keep my add-ons, I was simply renaming my user setting folder to match the downloaded one ('2.76' to '2.77' for instance), and then copied all downloaded files over existing ones, overwriting them. That works, but I'm not sure if that can introduce problems in the long run? And if there is a better way of doing the same thing (updating a portable install while keeping settings and add-ons)?
