i made a labyrinth. each folder had 10 subfolders with a single letter for a name. you had to spell out a phrase in order to find my porn. the trick was that the wrong subfolders contained more subfolers to convince you that you chose the right one until you had reached the end.
Consider the following facts, My computer is owned by nobody but me, as well as it's password protected. The folder my porn is located in is labelled 'pics' (instead of something like 'porn') which, there's about 4 or 5 folders with roughly the same name ALSO on my desktop.
Finally, I have a folder system that works for me; it starts with a word, it can be any word with a total of 6 or more letters (I'll use the word HIDDEN for my example, even if it isn't the word I actually used) So, when you open 'pics' you get 6 choices: H, H2, H3, H4, H5, and H6. In each of the H folders you'll find 6 I folders, then 6 D folders, and another D folder, and so on. Once you have your entire folder system in effect (which takes a while I'll admit) you hide your porn, this is a different system entirely.
Take each of of the six letters of HIDDEN, and rearrange them in alphabetic order (that would be D(1), D(2), E, H, I, N) This is the order in which you open your original folders. The first letter is D, which is the third letter of the word HIDDEN, if you're going in numerical order. This means you open the third of your original six H folders. In the next set of folders (the I folders) you open the fourth folder, since the next letter in numerical order is D(2) which is the 4th letter in HIDDEN.
In the end, the sequence for opening folders should be: H3, I4, D5, D1, E2, N6. In the N6 folder put ANOTHER folder labelled something non-porn sounding, like 'awesome', 'messed up', or like 'king' or something, anything you want really.
In the FINAL folder you put your porn, and as long as you remember your folder sequence you'll find your porn again.
