This final method allows users to hide files in a JPEG image:
1. Create a folder in C:, e.g. C:Folder1.
2. Put all the files you want to hide in there, as well as a JPEG image that you would like to hide the files in.
3. Select all of the files you want to hide, and create a ZIP or RAR file with them using a program like WinRAR, WinZip, 7Zip, etc.
4. Now you should have your archive next to your files that you want to hide, even though they are in the archived file already, with the JPEG image you would like to hide all of this in.
5. Go to “Start,” “Run,” and type: cmd.
6. Now type: cd , then type: cd Folder1. (Of course, replace Folder1 with the name of your folder.)
7. Type the following: copy /b myimage.JPG + archivedthing.rar myimage.jpg
(Note: Replace the name “myimage” with the name of your image, and replace “archivedthing” with the name of your compressed file.)
8. You should receive a response similar to the following: “1 file(s) copied.”
9. To find the files in your image, all you need to do is right-click on the image and select “Open With…” and select “WinRAR” or the name of the program you used to archive the original files.
