Why:

• Put files on your school share that your admins/teachers won’t see!
• Hide your password list file on your computer.
• Impress your friends
• and so many more!

What you Need:

• WinRar
• Basic command line knowledge

How:

1. Rar up the file you want, right click and choose “Add to *.rar”(if you need help for *nix/os x please join the forums and ask there!)
2. I normally put both files i want into a folder now
3. Go into command line and get into the folder your rar is at.
   • Windows: Copy /b ‘the image’ + ‘the rar’ ‘output filename’
   • Linux/OS X: cat ‘the image’ ‘the rar’ > ‘output filename’
4. Send the output file.
5. Receiver unarchives it with winrar and the files magically appear!

Examples

• Ok I have the file TutorialNinjas.jpg, and Passwords.txt in the folder HiddenCreate
• Now i will rar up passwords.txt(refer to step 1), this created a passwords.rar in the same folder.
• I open up a terminal/command prompt and navigate to the folder with passwords.rar and TutorialNinjas.jpg
  • Windows Users:
    • copy /b TutorialNinjas.jpg + Passwords.rar Picture.jpg
  • Linux
    • cat TutorialNinjas.jpg Passwords.rar > Picture.jpg
• Now if i open up the image it displays regularly
• However if i open it up in WinRAR i can view the hidden contents!
