user accessible INF file question

Hey everyone, just a quick question really.
Could any body direct me to proven resources (tuts etc) that show the possibility of incorporating inf files into unity… Can it be done?
Is this question a waste of space because its as simple as embarking on a file read method prior to an executable game loading.
(my thoughts are circling around skyrim etc where we can change stuff in the inf prior to loading the game)
I have to say , i will contiue to search but, any help here would be a great addition to anything i can gather on the subject…if , indeed, there is a subject here.
lol and thanks for reading this all dudes of the UDN

Standalone builds of your game can read files from the hard drive of the client machine using standard .Net file processing.
