A Sneaky Way to Hide Files
Suppose you worked for the CIA and you wanted to email a top secret file to a field agent deep behind enemy lines. A good way to do that would be to hide the file in a normal, innocent-looking photograph. I really don't know of any other good reason for hiding files in jpeg images but I do know how to do it. In fact you can hide as many files as you like inside a jpeg and they can be any kind of file whatsoever. But let's keep this simple and hide one text file in our jpeg. Here's how.
Start by creating a folder on the Root drive of your PC. We'll call this folder "test" or call it anything you want. If you don't know how to do that, don't worry. I'll explain it later. Now move the file or files you want to hide into this folder along with any regular jpeg. Oh, one tiny thing I failed to mention is, you're going need a copy of WinRAR. WinRAR is a file compressor sort of like WinZip. You can get a free copy at Downloads.com. If you can't find a free copy there, just Google "free winrar" and find someplace where you can download it for free. Don't pay for it.
You can try this with any file compressing program you happen to have handy. It may or may not work. I know it works with WinRAR.
