The above code to create an empty zip file is broken, as the comments state, but I was able to get it to work. I opened an empty zip in a hex editor, and noted a few differences. Here is my modified example:

FILE* f = fopen("path", "wb"); 
fwrite("\x50\x4B\x05\x06\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00", 22, 1, f);
fclose(f);

This worked for me. I was able to then open the compressed folder. Not tested with 3rd party apps such as winzip.
