So basically what I want, is any sort of program or anything that hides a certain document, archive, picture, video, paste, etc.
A bit of context would help, but encrypting it with a program like Truecrypt might serve your purpose.
I see someone wants to hide his porn folder :v:
Yeah, like something that makes a certain paste invisible and only I can view it by applying a password or using a program to reveal it back again. I'll check that one out.
What I did on xp:
Changed the Icon to a transparent one
Changed the Name to alt+0160
