Once logged in, you can hide files from the operating system, keeping pictures from showing in the gallery, movies from showing in the video player and more. Files can still be seen from a file manager app but this will keep things hidden from all but the most advanced users.

Obscura (Trial version) So you're ready to do more than just hide those images from the OS? Obscura is there to help you take your concealment to the next level.
