Masker is a program that encrypts your files so that a password is needed to open them, and then it hides files and folders inside of carrier files, such as image files, video, program or sound files.

The strong encryption up to 448-bit and password protection makes the hidden data inaccessible for unauthorized users! Only you using your password are able to open and extract your hidden files.

You can hide any files, and even whole folders with sub-folders! The carrier file will remain fully functional! Images can be viewed, sounds can be played and videos can be displayed on the monitor.

You can transfer the carrier file through the internet and the hidden files inside will be transfered simultaneously with the carrier file, because they are the part of the carrier file.
