Used Plain Sight for Windows?
Developer’s Description
By Void Realms
This program can be used to hide files within other files using military strength 256 bit AES encryption. For example you can hide your passwords inside your favorite vacation photo. The file you choose to hide inside of remains functional, for example, if you hide inside an image, the image still opens, prints, and looks the same. The only difference is the file size. When you hide data, an Unlock file is generated, that file along with your password are needed to extract the hidden data.
