Why? I regularly zip up both source and output. The structure
takes keeps them apart.
This sounds more like JayBird is selecting files in the right
hand side of Explorer and zipping them, then doing the same with
another project.
The trick is to select a folder on the left in Explorer and
zip that, then when you add the next project to the same zip file,
make sure the two folders have different names, then WinZip should
be OK.
That said, I think it better to have one project, source and
output, per zip file.
