Emergency Power Off in Face of Attacker

[Murraci]

In a case where a user must act swiftly to protect their data and press and hold the power button on their computer, are all folders locked and dismounted or must this be done manually to ensure files are safely encrypted? I've run a few tests and it appears that even if an application is running from an encrypted volume, it is indeed the case that everything is safely encrypted again upon log-in. Is this always the case?

A power off or reboot will unmount all mounted volumes. Considering Espionage protects data by copying them into encrypted mounted disk images, once the volume unmounts for which ever reason, the data will be stored in the encrypted disk image and not accessible without password....so in short, yes, if you hold down the power button and then start up your Mac, all folders will be locked.
