RouterOS updating, whith what?

Hello you all!!!
I have some 433 and I’m about to update the routerOS from 3.10 to 3.28. From what I been reading I couldn’t understand which is the difference between the different combination of files and packages available for downloading, and which I should use to make a complete update (or the best one you suggest). As far as I have seen the “all packages” download contains many .npk and the “compilation” have only one but is not that big. And other options like many files are also available, with all the options I’m not sure what is each one for and which is the one I need.

If some charitative soul could give me some explanation or tips would be magnificent

Thanks in advance for helping me to get in the Mikrotik world!!

Bye Andres

use the combined package
