There is other software that can do this kind of encryption. I was using EncFS, but i require decryption of whole 1TB folder structure be very fast and do not be PC resources hog for too long time. "Mounting" this folder structure would happen like once per month as i am sleeping my computer, not turning it off. But still decrypting 1TB of data on slow HDD seems bad idea comparing to Truecrypt containers which mounts in matter of seconds. So that is why i am looking for the SW similar to Truecrypt, but allows dynamic/flexible containers?
