Which program/files and from which GUI? Each GUI will have it’s own way of doing that, and on 99% of cases it’s not necessary. He consistently refuses to answer simple questions about what he’s ultimately trying to accomplish. I have a generic way of doing that, login with the root user. Do you think that’s a bad idea? Then list all of the reasons why using root as your main user is a bad idea and probably every single one will apply to what he wants as well. There’s a reason why programs that need root access ask for it and don’t expect you to run them with sudo, the “run as administrator” is a windows concept from an OS that doesn’t have a proper way to elevate privileges so programs can’t implement that API and you need to elevate the entire program.
