is there an app or a root code which I can use to password protect my files (music/videos etc) and contacts.
I know I can just secure device (autolock) but it would be handy if there was an app which can also do this and would let you secure files/content of your choice.

Sensitive data, you could store encrypted using 7z, openssl, decrypting every time you use it. But again don't get false sense of security by doing that.
