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.
