Yeah, you're right. I thought on the idea of a USB Drive, but here's the thing... I don't have one. I used to, but I'm pretty sure it broke. I'd ask my mom for one, but I'm pretty sure she would say know because I've been bothering her on Christmas gifts (And you heard it here first, I'm kind of an a-hole), and because she told me she spent over $2,000 on X-mas gifts for my whole family, I feel like I shouldn't bother her with that.
Actually, this morning I went on my home PC and uploaded a folder of the Doom Builder 2 files to drive, and successfully managed to download them onto my school one. The thing is, that my school computer doesn't have DirectX, so there's a problem right there. Still, I appreciate and thank you for your recommendations.
