Step 1: You will need two files - the file you want to hide and one jpg image - it can be of any size or dimensions. [If you want to hide multiple files in one jpeg image, just zip them into one file]
Step 2: Copy the above two files to the C: folder and open the command prompt window.
Step 3: Move to the c: root by typing cd \ [if the files are in another folder, you'll have to change the prompt to that folder]
Step 4: The most important step - type the following command:
copy /b myimage.jpg + filetohide.pdf my_new_image.jpg
To recover the original PDF file, just rename my_new_image.jpg to filename.pdf.
Here we illustrated with an pdf file as that works with simple renaming. If you want to apply this technique to other file formats like XLS, DOC, PPT, AVI, WMV, WAV, SWF, etc, you may have to first compress them in RAR format before executing the copy /b DOS command.
