Here’s how to hide files in a jpeg image.
1 First make your RAR/zip file. Fill the archive with whatever you need to hide.
2 Then select an image you want to hide.
3 Move both of these files to an empty folder.
4 Without having anything selected in the folder, hold shift and right click any empty space an go to “Open Command Window Here”.
5 This command will merge your files
copy /b [image].jpg + [archive].rar/zip [combined].jpg
Pretty self explanatory. Replace [image] with your image name, [archive] with your RAR/zip file name and [combined] with what you want the new image to be called.
Example: copy /b totse.jpg + molotov.rar molotov_everything.jpg
Image example
Your file is now hidden. Keep in mind though that it’s still going to raise some eyebrows if an image that’s 400 X 400 is 700mb.
To open your hidden file, rename its file extension to .rar/zip and unzip the file as you normally would
Note: In order to rename file extensions, you must be able to view file extensions.
