OK, I've excluded the .user file.
You can simply create your own pfx file to overwrite the sourceforge one. Unless there is some pressing need, I'm not going to try to maintain two parallel solutions that differ only by this file. VS includes a button to automatically generate this file, doesn't it?
As for separating zipstorer, what is your reasoning behind this? I do not wish to for several reasons. I prefer a single exe file with no file dependencies if it is possible. And when VS 2010 ships, I will likely have to switch back to the C# Express version as I no longer have an MSDN subscription. If I remember correctly, in the Express editions it's easier to manage the solution with a single project for some reason (perhaps I'm making this up?).
