Hide Your Files In A JPEG [Old School]

[西风の狂诗]

1. Gather all the files that you wish to hide in a folder anywhere in your PC (e.g. : make it in C:\hidden).
2. Now, add those files in a RAR archive (e.g. secret.rar). This file should also be in the same directory (C:\hidden).
3. Now, look for a simple JPEG picture file (e.g. logo.jpg). Copy/Paste that file also in C:\hidden.
4. Now, open Command Prompt (Go to Run and type ‘cmd‘). Make your working directory C:\hidden.

5. 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.
6. 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!

This works by copying the compressed file in binary mode onto the end of the jpeg images. When the picture is opened, the jpg header says the length of the data and ignores everything below (the hidden zip, rar file). When the compression software like 7-zip, WinRAR opens the picture it looks for compatible compression headers and starts reading the file where-ever those begin.

I have absolutely no use for this, but this is one of the coolest things I've learned about computers in the last month. Thanks a lot. It's always fun to learn something new... As long as it's not English, math, science, you get the point.

If you go through the trouble of hiding such archives, then don't forget to encrypt the archive. So even if someone guesses your hiding method, he can't reveal its actual contents.

btw, this concept is called steganography.
