Hide files and data inside any file of your choice!!

To do that we will need a software called Camouflage. Don't worry, it's free. Camouflage allows you to hide files by scrambling them and then attaching them to the file of your choice. This camouflaged file then looks and behaves like a normal file, and can be stored, used or emailed without attracting attention.

For example, you could create a picture file that looks and behaves exactly like any other picture file but contains hidden encrypted files, or you could hide a file inside a Word document that would not attract attention if discovered. Such files can later be safely extracted. For additional security you can password your camouflaged file. This password will be required when extracting the files within. You can even camouflage files within camouflaged files.

How to camouflage files?

 After installing Camouflage you will find two new menu options when right-clicking files in Windows Explorer; 'Camouflage' and 'Uncamouflage'. You can camouflage a file or several files at a time by highlighting them in Windows Explorer, then clicking the right mouse button and choosing 'Camouflage' from the pop-up menu.

A list of the files chosen is displayed in the Camouflage dialog. You can view/edit the files by double-clicking them with the mouse. Anyway, to continue click 'Next'.

In the second screen choose a file to be used as camouflage. This can be any type of file, but some files work better than others. For example, avoid choosing a text file because Notepad would display the entire contents of it, including the scrambled files attached. Most other files work well. Once you have selected a file, click 'Next'.

From the third screen choose the folder and filename of the camouflaged file that will be created.
Check 'Read-only' to create the camouflaged file with its 'Read-Only' attribute set. This is recommended because it makes the file safer, and prevents other applications from modifying it and destroying the camouflaged section. Click 'Next'.

From the final screen you can type in a password if you wish. This password will be required when extracting files from your camouflaged file. If you do not wish to add a password just click 'Finish'. Clicking 'Finish' will create the camouflaged file and then exit.

How to extract a camouflaged file?

To extract the files hidden within a camouflaged file, right-click it in Windows Explorer and choose 'Uncamouflage' from the pop-up menu.

A password prompt appears in the Uncamouflage dialog. If this file was created with a password, type it in. Once you have entered the correct password (if applicable), click 'Next'.

The second screen displays a list of the files hidden within the camouflaged file. The first file in the list is the file originally used as camouflage. Select the files you want to extract and click Next. Choose the folder where the file will be extracted and click Finish. Bingo!! you got back your hidden file.

Remember, that the file size of the final file will be a sum of the file size of both that file and the hidden files. So don't try to hide a 700MB file into a 20KB text file. A 700MB text file is sure to cause suspicion.
