I don't know if this counts as a Tech Talk thread or a Help! thread, but this is just as related to my "life" as it is my computer.

I am a kid, living with my parents. I wanted a mod for one of my computer games, but my mom just wasn't going to download it (at least not any time soon), so I went ahead and did it myself.

I need to cover my tracks well. Currently, I have the mod hidden in a folder I delegated to my game's "extra" stuff. Does anybody have advice, technological or otherwise?
