Ran some tests on WinZIP 8.1

It works in a similar fashion, it generates a (exactly) 64kb long file, with compressed data appended to it, I'm not sure how big the EXE itself is, but my .ZIP file was definatelly appended to the .EXE file also, it was compressed, the files were compressed within the EXe so my only guess is that the base EXE itself has decompression routines (PKUNZIP).
