Well this is really helpful. I share my computer(something very inconvenient) and I've always had the fear, since I start to be very interested in BL, that someone else in my family would discover my files, pics, etc. Thing that happend, with my brother, and was a mini caos between us, but I explained to him in a very assertive way which was all about, and he understood (luckly because he didn't bothered me anymore about it), so from there on, I haven't had any problem.
My method wich is quite simple and not very safety, but works for me with my notebook(when I use it) it's to create 2 or 3 (or more) folders with random names one inside of the other, like nouns not related to the content. Believe me, people don't get aware of what's going on inside those folders, I tasted it XD
The thing with ecrypted folders, is the probability of losing them. A friend of mine who works with computers and helps me to maintain mine told me that it's almost imposible to recover a folder wich has been ecrypted with a password after losing the pass. Once you forgot your password you're well...screwed. I know you have to be careful with that, write down the pass on a piece of paper or in a document, but you never know what could happen with that piece of important information.
But this is good to be known. How to preserve folders with your stuff and not having uncomfortable situations in the future...Thank you for the advice and the methods, they're always welcomed.
