Thanks to everyone who replied.
However, no one actually suggested a way to get what I needed. I know
encryption is good, and I know not letting strangers in my apartment is good,
and I know that if a bad guy gets access to my computer he can do many nasty
things.... I just don't know how to automatically delete the folder I
mentioned from my system! That was my question, and I would welcome some
suggestions on that.
For the time being, I deleted the folder manually (the one inside with the
name of the DVD, not the entire one) and keep using BleachBit to clean the
system. I actually think it's a software to be used even if you use
encryption. It cleans a lot of trash in the system.
