Activity 6-6: Using Disk Compression
Time Required: 10 minutes
Objective: Set the compression attribute on folders and files.
Description: You want to understand the compression attribute on an NTFS volume, so you set
the attribute on some files and folders, and then copy and move the files to see how compres-
sion behaves.
1. Log on to your server as Administrator, if necessary.
2. Open Windows Explorer, and click to open the QData volume. Create two folders named
Ctest1 and Ctest2 .
3. Right-click Ctest1 and click Properties . Click Advanced . In the Advanced Attributes dialog
box, click the Compress contents to save disk space check box, and then click OK twice.
Note that the Ctest1 folder's name is blue.
4. Click to open the Ctest1 folder, and create a text document in it named Test1 . Note that the
Test1 filename is blue, indicating that it's compressed. Open Test1 , type your name, and then
save and close the file. Access to the compressed file is transparent, meaning you didn't have
to do anything special to open it.
5. Copy Test1 and paste it in the same folder. Rename this file Test2 .
6. Right-click and drag Test2 to the Ctest2 folder. Release the right mouse button and click
Move Here . Click to open the Ctest2 folder. Note that Test2 is still compressed. Press Ctrl+Z
to undo the last action. Test2 is moved back to the Ctest1 folder.
7. Right-click and drag Test2 to the Ctest2 folder. Release the right mouse button and click
Copy Here . Click the Ctest2 folder. Notice that Test2 isn't compressed because copied files
inherit the compression attribute from their parent folders, and moved files retain their com-
pression attribute (unless moved to a different volume). Close any open windows.
Activity 6-7: Using File Encryption
Time Required: 20 minutes
Objective: Use EFS to protect sensitive files.
Description: You want to instruct users on how to encrypt files on their computers. You decide
to perform some tests so that you have a solid understanding of how encryption works.
1. Log on to the domain from your Vista computer as testuser1 with Password01 .
2. Click Start , Computer . In the left pane of Windows Explorer, click to open the Public folder
under Favorite Links. Double-click the Public Documents folder to open it.
3. Create a text file in the Public Documents folder, and name it Encrypted1 . Open the
Advanced Attributes dialog box for Encrypted1, click the Encrypt contents to secure data
check box, and then click OK twice. When you get the Encryption Warning message, click
the Encrypt the file only option button and Always encrypt only the file check box, and then
click OK .
4. Open Encrypted1 in Notepad, and type your name in it. Save the file, and exit Notepad.
5. Open the Advanced Attributes dialog box for Encrypted1, and click the Details button.
Notice that testuser1 is listed as a user who can access the file, and Administrator is listed
as a recovery agent. Click Add . Only testuser1's certificate is listed because no other user has
been issued an EFS certificate on this computer. Click Cancel twice, and then click OK twice.
6. Log off and log on as testuser2 with Password01 . Navigate to the Public Documents folder.
Double-click Encrypted1 to open it. You get an Access Denied message. Click OK , and then
exit Notepad.
7. Create a text file named Encrypted2 . Set the encryption attribute on the file, and then click
OK until all Properties dialog boxes are closed. Open the Advanced Attributes dialog box
