Question about PPCLink dot com

I found a link to ppclink.com in the PDA's and Programs thread. I downloaded the edictionary reader, and it looks like a useful function, but I can't figure out what to do with the dictionaries I downloaded.

They are ZIP files--where do I put them in my PDA so the dictionary reader can find them? How do I choose which dic I want to use? I put them all in one folder but the reader doesn't seem to recognize them at all.
