Adobe After effects Mac/PC compatibility question

I have been offered to do some freelance rotoscope work for a production using after FX on PCs. However, the only computer I have access to with After FX loaded is an iMac G5. I was wondering how compatible the files are. I will basically just be opening projects that they may already have worked on with PCs onto a mac, putting in the mattes they want and returning them to the post-production team for compositing on their high-spec PCs.

So, effectively, I need two-way compatibility. I realise the old rule of macs reading Windows files but not vice-versa, but there are many exceptions like Office etc. I am hoping the same is true of adobe's software. I am assured by the friend who got me the work that this won't be a problem, as he's done it before, but I need to make sure before I commit.

Please help.

 

Cheers for the swift response and thank you for allaying my fears. When you put it like that, I guess it was just my experience with ipods and hard drives that was concerning me. Having said that, they seem to think I'll be writing the files to a external lacie, which they'll then be able to read. Now that should present its own set of problems...

 

Thanks again. I guess I'm employed after all. Cheers for all your help guys.
