You use a desktop computer that has Windows 7 Ultimate SP1. The relevant portions of the computer
configuration are shown in the following exhibits:
· The Disk Management console (Click the Exhibitbutton.)
· The System Properties window (Click the Exhibitbutton.)
· The System protection for Local Disk C window (Click the Exhibitbutton.)
You encrypt several files on an external USB hard disk drive by using the Encrypting File System (EFS).
You need to ensure that you can access the files from another computer.

Explanation:
* cipher /x[:efsfile] [<FileName>]
Backs up the EFS certificate and keys to the specified file name. If used with :efsfile, /x backs up the user’s
certificate(s) that were used to encrypt the file. Otherwise, the user’s current EFS certificate and keys are
backed up.
* Back Up Your EFS Key
The first time that you use EFS to encrypt something, your system generates a random 256-bit number; that’s
the key that EFS uses whenever you encrypt something. To back up your EFS key, simply use the Cipher /x
command. Cipher will reply with a message asking ifyou truly want to back up your EFS key–sadly, I haven’t
found a way to suppress this message. Press OK. Thetool will then prompt you for the name of the filein which
to store the backup. Don’t specify a file extension; Cipher insists on the .pfx extension. For example, if you
picked a file named mybackup, you now have a small file called mybackup.pfx. Next, the tool will prompt you to
create a password with which to protect that file.
Once you’ve got that file created, copy it from your computer’s hard disk to some offline location (e.g., a USB
stick, a CD-ROM) and make a note of the password you’ve chosen. Now, in the event of unfortunate
circumstances– for example, you lose your profile,you forget your password and a systems administrator has
to reset it, the system’s OS fails and you need to recover files directly from the nowdead system’s hard disk–you can simply restore your EFS key by double-clicking the .pfx file and running the resulting wizard.As soon
as the wizard is finished, you’ll be able to get toyour files again.
