Umm... But WinZip is free. And would probably compress your original
executable content to something smaller than your first attempt to send it.
Perhaps not as small as RAR, but so what? You already were willing to send it
uncompressed. And repeatedly! ;) So I don't see your point.
When a client asks for format "X", give them format "X". Why send them format
"Y" and then complain when it doesn't work?
Self-extracting executables are just as dangerous as any other executable
content; so, expect them to be filtered out by many, many systems. Also, most
AV scanners can scan a .zip file. How many, I wonder, can scan a RAR file?
