How can I get an Adobe CS5 document to be able to be viewed in the CS3 version?

[horsebkridr]

I just bought Adobe CS5 and when I tried to open some projects at school (they have CS3) it wouldn't let me because I had used the newer program. Is there anyway to be able to view them without the school updating or is there a way for me to save it as a CS3? Please help me. I just spent a lot of money on CS5 and I don't want it to go to waste because I can't open it at school. Thanks!

Save in compatibility mode. When you go to save, it should ask you if you want to do this. This will significantly increase the filesize but will allow backwards compatibility and it should be backwards compatible with CS3.

Well, for what you can do with saving files backwards in CS5, it depends on which program or product you're talking about...
