Sending zip files and other badass files like exe, com (lol, I said com files)

If you send a zip, exe, osx, dll, com, bat, or any other "dangerous" file as an attachment in gmail, it'll claim it's malicious and refuse to send it. You could use file transfers like box.net, megaupload and rapidshare. But they cost $$ and you need to train the receiver on how to get the file. So, here is a tip: If it's a zip file, rename the extension of the file from ".zip" to ".dat" and send it! This goes for dll, exe, osx, bat, and com (haha) files too. If you have more than one badass file, zip them all up and rename the extension to .dat first. Then send it!!!
