Here's how its done. First all you need is 7-zip and command prompt. Once you have the files you want to hide and the image file open 7-zip. Locate the files you want to hide and add them to a .7z file. Make sure these are selected:
- Archive format:7z
- Compression level: Ultra
- Compression Method:LZMA
- Dictionary size: 64MB
- Word Size:64.
Once done you can delete those files you were trying to hide because they are now in the .7z file you just made. Open command prompt by going to start run and put in cmd. to make it easier make a folder on your desktop and put the .7z file and the .jpg file in the folder so its all in one place.
Lets call the folder its in x123 the .7z file shadow.7z and the .jpg return.jpg. So now in command prompt it should say c:/ documents and settings> "your pc's name">. Now next to that put cd x123 so it opens the folder it should now be c:/ documents and settings>"Your pc's name">x123>. After that put in COPY /B return.jpg + shadow.7z returnsecret.jpg after this it should say 1 file copied and there should be a new .jpg file in your x123 folder called returnsecret.jpg.
To get the files off of the new image file lets say you had passwords there and you need to get them back open 7-zip again and select returnsecret.jpg now press the extract button. There should now be a folder called returnsecret with the files you just hide inside the image. You can delete this folder and extract it again from the image over and over. Hide it in a thumbdrive,psp,external drive, iPod, or any mass media and only you will know that the files are there or even how to extract them.
