In order to accomplish this task, you will need to have either WinZip or WinRAR installed on your computer. You can download either of these two off the internet and use them without having to pay anything. Here are the steps for creating your hidden stash:
1.Create a folder on your hard drive, i.e. C:\Test and put in all of the files that you want to hide into that folder. Also, place the image that you will be using to hide the files in.
2.select all of the files that you want to hide, right-click on them, and choose the option to add them to a compressed RAR file. Only select the files you want to hide, not the picture. Name it whatever you want, i,e. “Hidden.rar”.
3.Now you should have a folder that something like with this files, a JPG image, and a compressed archive
4.Click on Start, and then click on Run. Type in “CMD” without the quotes and press Enter. You should now see the command prompt window open. Type in “CD \” to get to the root directory. Then type CD and the directory name that you created, i.e. “CD Test“.
5. Now type in the following line: “copy /b DSC0005.JPG + Hidden.rar DSC06578.jpg” and press Enter. Do not use the quotes. You should get a response like below:
you can see
Just make sure that you check the file extension on the compressed file, whether it is .ZIP or .RAR as you have to type out the entire file name with extension in the command. I have heard that some people say that they have had problems doing this with a .ZIP extension, so if that doesn’t work, make sure to compress to a .RAR file.Quote:
c:/test>copy /b DSC06578.JPG + Hidden.rar
DSC0005.jpg
1 file(s) copied.
And that’s it! The picture file will have been updated with the compressed archive inside! You can actually check the file size of the picture and see that it has increased by the same amount as the size of the archive.
You can access your hidden file in two ways. Firstly, simply change the extension to .RAR and open the file using WinRAR. Secondly, you can just right-click on the JPG image and choose Open With and then scroll down to WinRAR. Either way, you’ll see your hidden files show up that you can then extract out.
The JPEG file format allows it to embed additional information called "metadata" in the file header.The purpose of these metadata is to provide additional and useful information along with the picture. Image manipulation programs and especially digital cameras take advantage of this feature. you can add detais to specifications which are the IPTC headers .More detailed information about these metadata formats as well as descriptions of other metadata formats can be found at here http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/
