Which is a step in using FTK to recover EFS encrypted files?

When recovering EFS (Encrypting File System) encrypted files using FTK, noting the encrypting Windows user is a vital step in the process. EFS relies on user-specific certificates and keys that are tied to the account of the user who encrypted the files. Without access to these credentials, decrypting the files becomes significantly more challenging. Therefore, identifying the encrypting user allows the examiner to locate the necessary encryption keys associated with that user's profile, which is essential for successful file recovery.

Other options, while may be beneficial in certain scenarios, do not directly pertain to the specific context of recovering EFS encrypted files. For example, running a vulnerability scan could be relevant in assessing system security but does not assist with file decryption. Likewise, deleting unnecessary files can free up space or reduce clutter but has no impact on recovering encrypted files. Rebooting the device is a standard troubleshooting step in many IT scenarios but does not contribute to the process of accessing encrypted data.
