To move a compressed file to an uncompressed folder
2. Is the Text1.txt file in the Compressed folder compressed or uncompressed?
Uncompressed. A new file inherits the compression attribute of the folder in which it is created.
3. Is the Text1.txt file in the Compressed2 folder compressed or uncompressed?
Why?
Compressed. When a file is moved to a new folder on the same partition, its compression
attribute does not change.
Lesson 2 Review
1. When Sandra tried to copy a compressed file from one NTFS volume to another,
the file was not copied, and she got an error message stating that there was not
enough disk space for the file. Before she attempted to copy the file, Sandra verified
that there was enough room for the compressed bitmap on the destination
volume. Why did she get the error message?
If you copy a compressed file to an NTFS volume with enough space for the compressed file,
but not enough space for the uncompressed file, you might get an error message stating that
there is not enough disk space for the file. The file will not be copied to the volume.
2. When you move a file between NTFS volumes, does the file retain the compression
state of the source folder, or does the file inherit the compression state of the
target folder? Why?
When you move a file or folder between NTFS volumes, the file or folder inherits the compression
state of the target folder. Windows XP Professional treats a move as a copy and then a
delete, so the files inherit the compression state of the target folder.
3. What does Windows XP Professional do when you try to copy a compressed file
to a floppy disk? Why?
When you copy a compressed file to a floppy disk, Windows XP Professional automatically
uncompresses the file because floppy disks cannot be formatted with NTFS and cannot use
NTFS compression.
4. Which of the following types of files or data are good candidates for NTFS compression?
(Choose all that apply.)
a. Encrypted data
b. Frequently updated data
c. Bitmaps
d. Static data
The correct answers are C and D. A is not correct because you cannot apply both compression
and encryption to a file. B is not correct because compression does add some overhead when
accessing files, so you should not use it on files that you access frequently.
