Finally I've found a tool that works under Windows 7 64bit and should therefore also work under Vista.
The first time you run the tool you need to press the "UT 2003 Dir" button, navigate to
\Steam\steamapps\common\killingfloor\System and double click the ucc.exe.
Then simply select the files you want to compress, click Add Files and then Compress
