Are Photoshop CS1 .psd's compatible with CS2?

I'm only posting this because I need an answer ASAP. I have a Photoshop assignment for one of my classes and we use CS2 at school, but I only have CS1 at home. So I just want to know if anyone knows for certain that CS1 .psd's will open with CS2. Thanks!

this isn't definite but I'm pretty sure it should work. I've used cs2 files with 7 pr 8 I think and it worked fine both ways.
