drag and drop the .catalyst into a notepad.exe document. Data will start to show.
What we are looking for is the header. many times when a program is compressed and has other files in it then the header will show files compressed and how it was compressed with what tool it uses like gzip or something. The header is usually the first 3 to 15 lines at the top of the notepad.exe document.
Majority of the file will look like junk data.
