• Some times, we have to hide some files for particular reason like classified files and we do not want it be found by others.You just need :

• Image File or PDF File

• Files which are going to be hidden

• Archiver Application (WinRar, 7Zip, etc.)

• Command Prompt

• Now just follow this steps :

1. Compress your files and make them as archive file. In this example, I'm going to hide my test.rar file into my PDF (readme.pdf)
2.  Open your Command Prompt and run it As Administrator, direct to your files location, then type this command exclude quote marks : "copy /b readme.pdf + test.rar redme.pdf". Please adjust readme.pdf with your own PDFfile, test.rar with your own compressed file, and redme.pdf with your own new PDF name and this is up to you to give the name. After that, click ENTER button.
3.  If you did it right, you will get a New PDF files with bigger file size, because the binary codes between test.rar and readme.pdf are combined into one file is redme.pdf
   
4. To open your hidden files, you just open your archiver application, in this example is WinRar. Go to your PDF files and extract it. You will get new folder named redme and you will find your test folder inside it.
