You will never see any piece of equipment the cops took ever again. Consider it G-O-N-E.
1. You are 16...you kept everything on your system HD...hiding it in a subsubfolder won't hide squat.
2. If you're gonna do this kind of stuff, keep it on a separate HD, that is not normally installed on your PC...hide the HD somewhere FAR away from the PC itself..only plug it in when doing whatever it is you do. This way, when they snatch your PC, they don't get anything. That said.....
3. You were dumb enough to get caught. [ralphvoice]Ha-Ha![/ralphvoice] The DA will make an example out of you, and you deserve it, to teach you a lesson and to show the other young punks what will happen if they follow in your footsteps.
4. You will need a lawyer. NOT the state-appointed one, else you're gonna get screwed.
5. WITH your own lawyer, you will get a fine (prolly in the neighborhood of $1K) and so much community service that you won't have a weekend for the next year or so. Consider yourself lucky.
6. WITH your own lawyer, you will get no jail time. You are a minor. Waitaminute, you're not a Juvie Offender, are you? I hope for your sake this is your first real run-in with The Law...if not, you may be graduating HS a year or so late.....
You are about to learn about the way the world works, young man. You'll be a better adult for learning your lesson now.
