Most of the information here is for Warzone 3.1 and above.
Warzone Zips (.wz)
What is a .wz file?
It's just a .zip file that's renamed to .wz.
How do I create / open them?
info to follow
Windows
To open a .wz file, either rename it to a .zip file, or try to open it with a program such as WinRAR or 7-zip.
To create a new .wz file, you could either copy one of the existing .wz files, open it, then edit away, or you could create a new .zip file, add all the necessary stuff, then rename it into a .wz file.
Linux
Mac OS X
Mac OS X has native support for zip files and will usuall recognise a .wz file as a zip – simply double clicking a wz will usually unarchive it (deleting the .wz file automatically and replacing it with a folder of the same name).
To create a zip file on a Mac, select the files to compress, right click and then choose "Compress", then rename the resulting .zip file to .wz. Be sure to test that it still works by moving the uncompressed items somewhere else – sometimes there will be an unwanted top-level folder in your zip.
What should be in them?
