1 5.1 © 2004 Pearson Education, Inc. Exam 70-290 Managing and Maintaining a Microsoft® Windows® Server 2003 Environment Lesson 5: Working with File Systems Goals  Understand File Allocation Table (FAT)  Understand NTFS  Compress and encrypt data on an NTFS Volume  Assign shared folder permissions  Set NTFS permissions  Set special access permissions  Troubleshoot permissions  Understand Distributed File System  Manage a Dfs Root

2 5.2 © 2004 Pearson Education, Inc. Exam 70-290 Managing and Maintaining a Microsoft® Windows® Server 2003 Environment Lesson 5: Working with File Systems  An older file system that can be read and accessed by most operating systems such as DOS, Windows 3.x, Windows 9.x, Windows NT, Windows 2000, Windows XP, and Windows Server 2003  FAT allocates storage space to files by setting up allocation units on a hard disk  An allocation unit, also known as a cluster, is the smallest unit for allocating storage space on a partition or volume  Sectors are the basic units of the physical drive and are the smallest units that can be used to transfer data to and from the disk (Skill 1) Introducing File Allocation Table (FAT)

4 5.4 © 2004 Pearson Education, Inc. Exam 70-290 Managing and Maintaining a Microsoft® Windows® Server 2003 Environment Lesson 5: Working with File Systems  Two primary versions  FAT16 file system  Supports partitions of up to 4 GB in size  Only Windows NT, Windows 2000, Windows XP, and Windows Server 2003 support FAT16 partitions larger than 2 GB  Is efficient on small-sized partitions of up to 256 MB  Supports dual booting by all Microsoft operating systems  Provides only folder-level security  FAT32  Similar to FAT16  It supports large-sized partitions of up to 2 TB (2047 GB) Introducing File Allocation Table (FAT) (2) (Skill 1)

5 5.5 © 2004 Pearson Education, Inc. Exam 70-290 Managing and Maintaining a Microsoft® Windows® Server 2003 Environment Lesson 5: Working with File Systems Figure 5-2 The FAT file system (Skill 1)

6 5.6 © 2004 Pearson Education, Inc. Exam 70-290 Managing and Maintaining a Microsoft® Windows® Server 2003 Environment Lesson 5: Working with File Systems Reliability  NTFS is a recoverable file system  Volumes can be created that do not result in data loss in the event of a server crash or power failure Security  You can secure data by setting up permissions to control user access to files and folders Long file names  NTFS natively allows file names to be up to 256 characters in length Efficiency  NTFS is required in order to use certain features, such as Active Directory, which stores and manages network resources efficiently Faster access  NTFS minimizes the number of disk accesses required to find a file, which increases access speed Introducing NTFS (Skill 2)

7 5.7 © 2004 Pearson Education, Inc. Exam 70-290 Managing and Maintaining a Microsoft® Windows® Server 2003 Environment Lesson 5: Working with File Systems Data compression  Built-in feature that increases available storage on a hard disk  In NTFS volumes, you can compress only specific files and folders or the entire volume  When you add a new file or folder to a compressed folder, it is compressed automatically  You cannot compress an encrypted file Data encryption  A security technique that attempts to ensure the confidentiality of a document by scrambling it using an encryption key  You cannot encrypt a compressed file Compressing and Encrypting Data on an NTFS Volume (Skill 3)
