Actually not so simple.  It was prepared to go to a larger format but 
the size of your disk in kbytes overflowed a 32-bit signed integer!
I have changed the format to display Mbytes instead of kbytes - more 
suitable to the modern world and more readable.  That meant 11 copies of 
ZFRE2 plus one of ZFREE to change.
