but how do you get all of the files into one file and ready to download?, or can you put more than one file into it when you submit?
Get WinZip and read its manual.
Zoner's tools? Search the forums for info, or just look at the Links page for the URL to the tools themselves.
What's the diff between WinZip and the compression built into XP? That's what I use.
None technically (although WinZip 9 now includes a stonger compressing algorithm that's proprietary (only their software supports it).
RARs seem better when I last compared them.
