for me my friend, i think it defeats the purpose of hiding something if you are putting it in plain sight. even if it is encrypted.
challenger application can be put in a desktop as an application. would ask for a password/keypass and you can access/decrypt all your fave encrypted folders wherever they are hiding in the computer. it all depends on how you wanna use the application i think. i'll try to ask my friend if have a free software in mind that would meet your needs.
