Yes and no full disk encryption think about it just preventing something like your friend co-worker attacker, from not being able to access your files say if you take the drive and plug it into another computer, they couldn't read the contents of the files. But pretty much as soon as you boot your computer type in the password the contents are no longer secure. Like linux lets you encrypt the contents of your home folder, but for windows or even mac OSX I really don't think having every file encrypted is a good idea. Like you could leave the OS files and anything else that isn't private alone, and then make sort of a few folders with your personal stuff fully encrypted. So you could have something like 3 layers of protection like a BIOS password, then you could encrypt you hard drive so no one can access the contents without knowing the password, then you could encrypt your personal files. Then do something like I mentioned before and use something like a txt file and store your passwords in a txt file then encrypt that with a decent password that you already know with AES.
But yes vera will encrypt your entire disk if you want.
