What option in FTK Imager allows you to obtain registry files from a live system?

The option that allows you to obtain registry files from a live system in FTK Imager is the "Export files option." This functionality is specifically designed to access and extract files from a live operating system, including system files such as the Windows registry. The registry files are critical for forensic analysis as they contain vital information about the system configuration, user preferences, installed software, and more.

The "Export files option" enables examiners to simply navigate through the file structure of the live system and select the registry files they wish to export, thereby facilitating a more straightforward approach to gathering this data without the need for imaging the entire disk.

The other options, while useful in different contexts, do not specifically focus on the export of registry files from a live system. The "Image file option" is typically used for creating copies of disk images, while the "Capture memory option" is focused on obtaining a snapshot of the system's volatile memory. The "Extract evidence option" generally pertains to pulling out specific evidence from a disk image rather than directly working with live system files.
