FAT file systems• Use Disk Management to view information

about disks and partitions

Windows 7 for Power Users Tutorial 5 2

XPXPXPXPXPXPObjectives• Compress and uncompress folders and files• Create and extract compressed folders• Encrypt and decrypt folders and files• Examine BitLocker Drive Encryption


XPXPXPXPXPXPDisk Management


XPXPXPXPXPXPThe Windows 7 File Systems• NTFS (New Technology File System)• FAT (File Allocation Table) or FATFS (File

Allocation Table File System)• Extended FAT file system (exFAT)• UDF (Universal Disk Format)• CDFS (Compact Disc File System)• Live File System


XPXPXPXPXPXPFormatting a Hard Disk


XPXPXPXPXPXPFormatting a Hard Disk• Low-level formatting – creating tracks and

sectors on a disk• High-level formatting – creating a file system

on the disk


XPXPXPXPXPXPUnderstanding the Role of the Master Boot Record• Plays an important role in the booting process–Contains information about the partitions• Hard Disk Partition Table

–Contains Master Boot Code• Boot sector or boot record


XPXPXPXPXPXPExamining the Native File System of Windows 7• Native file system for Windows 7–Master File Table (MFT)•Master File Table Mirror (MFTMirr)•Metadata•Media descriptor• Transaction log file• Self-healing


XPXPXPXPXPXPExamining the Native File System of Windows 7• Comparing MFT attributes– Archive– Read-only– Hidden– System– Compress– Encrypt– Not Content Indexed– Directory– Symbolic link


XPXPXPXPXPXPExamining the Native File System of Windows 7


XPXPXPXPXPXPExamining the Native File System of Windows 7• Contains additional features not available in the FAT

file systems– Folder and File Permissions– GUIDs– Multiple Data Streams– Disk Quotas– Mounted Drives– Hard Links– Sparse Files– Encryption– Compression


XPXPXPXPXPXPUnderstanding the FAT File System• Introduced with the first version of DOS• Creates the following four tables in the system

area of the disk:–Boot record– File Allocation Table #1 (FAT1)– File Allocation Table #2 (FAT2)–Directory table


XPXPXPXPXPXPUnderstanding the FAT File System

Cluster Usage in the File Allocation Table Directory Table for Top-Level Folder


XPXPXPXPXPXPUnderstanding the FAT File System

Cluster Sizes for FAT16 Volumes Cluster Sizes for FAT32 Volumes


XPXPXPXPXPXPChecking the File System of a Drive• The volume label is the name assigned to a

disk• Right-click the drive and then select Properties

to view the file system


XPXPXPXPXPXPUsing the Disk Management Tool• Microsoft Management Console (MMC)

provides access to administrative tools


XPXPXPXPXPXPUsing the Disk Management Tool• Right-click the Computer icon on the desktop (or Start

menu), click Manage, and then click Disk Management under Storage in the Console tree in the left pane of the Computer Management window

• To more clearly identify the two areas in the Details pane, click View on the menu bar, click Customize, and in the Customize View dialog box, click the Description bar check box to enable this feature, and then click the OK button

• To view disk information by disk number and CD number, click View on the menu bar, point to Top, and then click Disk List


XPXPXPXPXPXPAttributes


XPXPXPXPXPXPCompressing and Uncompressing Folders and Files• NTFS volumes allow you to compress files, folders, or

an entire drive– Decompresses and recompresses files as you work

• To compress a folder:– Right-click the folder– Click Properties on the shortcut menu– Click the Advanced button– Click the Compress contents to save disk space

check box– Click the OK button


XPXPXPXPXPXPCompressing and Uncompressing Folders and Files


XPXPXPXPXPXPCompressing and Uncompressing Folders and Files• To uncompress folders and their contents,

perform the same steps as you did to compress the folder and its contents, but remove the check mark from the Compress contents to save disk space check box


XPXPXPXPXPXPUsing Compressed (Zipped) Folders• NTFS and FAT volumes support Compressed

(zipped) folders–Contains a group of files in a single file–Makes it faster to upload multiple files–Windows 7 uses a custom icon with a zipper

• To compress a folder:–Right-click the folder, point to Send To, click

Compressed (zipped) Folder, and then press the Enter key


XPXPXPXPXPXPUsing Compressed (Zipped) Folders


XPXPXPXPXPXPEncrypting and Decrypting Folders and Files• The Encrypting File Service (EFS) encrypts folders and

files on hard disks– Encodes the data– Files retain encryption until you decrypt it• Be careful when moving files between NTFS and

FAT volumes and vice versa• To encrypt a folder and its contents:– Display the folder properties– Click the Advanced button– Click the Encrypt contents to secure data check box– Click the OK button


XPXPXPXPXPXPEncrypting and Decrypting Folders and Files


XPXPXPXPXPXPEncrypting and Decrypting Folders and Files• An encryption key is used to encrypt and

decrypt files• A certificate authority confirms your identity

and contains information used to protect data or to establish secure network connections–Certificate


XPXPXPXPXPXPEncrypting and Decrypting Folders and Files• BitLocker Drive Encryption can encrypt the

boot volume–Available in Windows 7 Enterprise and

Windows 7 Ultimate–Uses a Trusted Platform Module (TPM)

microchip on the motherboard
