Well, did you know you could hide your files in a JPEG file? For this, you will only need to download WinRAR. You just need to have a little knowledge about Command Prompt and have WinRAR installed.
Ok, lets begin…
- Gather all the files that you wish to hide in a folder anywhere in your PC (make it in C:\hidden - RECOMMENDED).
- Now, add those files in a RAR archive (e.g. secret.rar). This file should also be in the same directory (C:\hidden).
- Now, look for a simple JPEG picture file (e.g. logo.jpg). Copy/Paste that file also in C:\hidden.
- Now, open Command Prompt (Go to Run and type ‘cmd‘). Make your working directory C:\hidden.
- Now type: “COPY /b logo.jpg + secret.rar output.jpg” (without quotes) - Now, logo.jpg is the picture you want to show, secret.rar is the file to be hidden, and output.jpg is the file which contains both.
- Now, after you have done this, you will see a file output.jpg in C:\hidden. Open it (double-click) and it will show the picture you wanted to show. Now try opening the same file with WinRAR, it will show the hidden archive :).
Done!
You can also upload the image (output.jpg) on image host and share it with others :D.
Ok, so you want a test image? Well, you got it. Below is a test image I created for you.
Save this file in your PC. Then try opening it normally first and then open it with WinRAR. You’ll see the difference. 
Hope you like this post. Thanks for reading.
Enjoy!
Update (Sept. 11, 2007): I just checked the file link, and it seems to be down. I’ll upload the file again and update the link soon.
