Search files for hidden information - how it works

If you suspect secret information behind files, you can search the files for hidden messages. This guide shows you how this works with the Hex Editor MX.

Show the control code of files

1. Download the Hex Editor MX and run the program.
2. Click on the "File" tab at the top and then on "Open ...".
3. Use the Explorer to select the file in which you want to search for hidden information.
4. Now you see a whole list of numbers and on the right side the matching "translation".
5. Much of it will be unreadable for you. You will usually find secret messages at the very beginning or end.
6. You can also search for specific and commonly used keywords such as "that", "but" and "me". To do this, click on the Ferngals icon.
7. If the keyword is in the file, it will be marked by the hex editor MX. With a little luck, you will actually find some interesting information in some files. However, this only works if the message is in plain text and has not been encrypted.
