There are no stupid questions.

 Save File is natural attribute of the World, not someone's ability. As the one with the highest Determination is showing up in Underground, access to SF is given immediately to them. SF contains informations about state of the World (in this case about Underground) and state of everything that is inside that World. While the one is gaining access to SF, it collects information about state of the World and it does this only once. This set of data cannot be overwritten and can be used only by Reset function. Another, separate set of data can be manually made/updated (overwritten) in Save Points only by Save function. This data can be used only by Load function. The Reset, Save and Load functions are the way of managing the Save File. Intended purpose of RSL technology is to undo changes that has been made to the World.  Fun facts:

 If Save File contains information about The Surface, than it means that RSL affects Surface too.</li> If Save File contains information about the whole World is true, than you can determine exact size of that World</li> </ul>
