When the wizard is finished, the files are copied to the location that you had previously specified. The ASR floppy disk is ready for use in the event of an ASR restore operation. NOTE: The Asr. sif and Asrpnp. sif files must reside on the root of the floppy disk drive to be used during a ASR restore operation. ATTENTION: Content on the A+ 220 -701 Essential Exam ends here! 66
Managing Files, Folders, and Hard Drives • Understanding of how to manage folders and files – Manage data, configure Windows, set up network resources, and keep the PC in good working order • Knowing where to look on the hard drive to find folders and files needed – Requires understanding of directory structures used by Windows Vista, XP, and 2000 67
Directory Structures • Know user files, system files, fonts, temporary files, program files, and offline files and folders • When a user first logs onto Vista, user profile is created and has two contents – User folder together with subfolders is the user profile namespace – Ntuser. dat in the user’s folder containing user settings • Windows Vista user account folder – Stored in C: UsersUsername • Windows XP user account folder – Stored in C: Documents and Settings folder – See pg. 643 Fig. 13 -41 68
Directory Structures (cont’d. ) • Other important folder locations – Windows registry: Windowssystem 32config folder – Registry backup: Windowssystem 32configReg. Back folder – Fonts: stored in the WindowsFonts folder – Program files (32 -bit versions) • C: Program Files – Program Files (Vista and XP 64 -bit versions) • C: Program Files (64 -bit programs) • C: Program Files (x 86) (32 -bit programs) 69
Directory Structures (cont’d. ) • Other important folder locations (cont’d. ) – Temporary files: WindowsTemp folder – Windows Vista temporary IE files: • C: UsersusernameApp. DataLocalMicrosoftWindows Temporary Internet Files – Windows XP temporary IE files: • C: Documents and SettingsusernameLocal SettingsTemporary Internet Files – Client-side caching (CSC) folder: C: WindowsCSC 70
Client-side caching (CSC) folder – This folder is created and managed by Windows Offline Files utility – Makes it possible for a user to work with a copy of folders and files stored on the local network, when the computer is not connected to the network 71
Client-side caching (CSC) • • • In todays highly competitive e-commerce marketplace, the performance of a web-site plays a key role in attracting new and retaining current clients. New technologies are being developed to help speed up the delivery of content to customers while still allowing companies to get their message across using rich, graphical content. However, in the rush to find new technologies to improve internet performance, one low-cost alternative to these new technologies is often overlooked: client-side content caching. This process is often overlooked or dismissed by web administrators and content providers seeking to improve performance. The major concern that is expressed by these groups is that they need to ensure that clients always get the freshest content possible. In their eyes, allowing their content to be cached is perceived as losing control of their message. This bias against caching is, in most cases, unjustified. By understanding how server software can be used to distinguish unique caching policies for each type of content being delivered, client-side performance gains can be achieved with no new hardware or software being added to an existing website system 72

Windows Dynamic Disks • Hard drives are normally configured as a basic disk • Basic disk uses MBR partition table • Win Vista Business, Enterprise, and Ultimate editions and XP Professional can use dynamic disk • Basic disk use MBR partitions, volumes and logical drives • Dynamic Disks use dynamic volumes, can span more than one hard drive • Data to configure each HD is stored in a Disk Management Database that resides in the last 1 MB of storage space at the end of a HD 91
Windows Dynamic Disks • Dynamic Disks considered more reliable than MBR method • Here are four uses of dynamic disks: – Better reliability can be allocated as simple dynamic volume – You can implement dynamic disks on multiple hard drives to extend a volume across these drives (spanning) – DD can be used to piece data across multiple hard drives (stripping or RAID 0) to improve performance – For XP, you can use dynamic disks to mirror two hard drives for fault tolerance (mirroring or RAID 1) not available for Vista 92
Windows Dynamic Disks • Better reliability, spanning, stripping (RAID 0) to improve performance, mirror two hard drives for fault tolerance (RAID 1) for XP Figure 13 -58 Basic disks use partitions to organize a hard drive, and dynamic disks use dynamic volumes to organize multiple hard drives Courtesy: Course Technology/Cengage Learning 93
Use Disk Management To Manage Hard Drives (cont’d. ) • Windows dynamic disks (cont’d. ) – Disk Management converts two or more basic disks to dynamic disks • Create spanned or stripped volume • Spanning and software RAID is not very safe Figure 13 -60 Create a spanned or striped volume. Courtesy: Course Technology/Cengage Learning 94
Cautions about Software RAID • When dynamic disks are used for spanning or RAID, catastrophic failure increases, can lead data loss • Microsoft suggests that you only use spanning or RAID with dynamic disks • If you have no other option, RAID be implemented using hardware RAID rather than using dynamic disks • Means, spanning and software RAID aren’t very safe – use hardware RAID instead • You cannot install OS on a spanned or striped volume that uses software RAID, but you can hw RAID • You cannot convert from dynamic to basic disk once 95 you converted to dynamic disk without losing all data
Use Disk Management To Manage Hard Drives (cont’d. ) • Drive and volume status indicators: – – – – Healthy Failed Online Active Unallocated Formatting Basic Dynamic • Offline, foreign drive, and healthy (at risk) 96
Regional and Language Settings • Configure computer to use a different language – – Download and install the language pack Change Windows display language Chang how numbers are formatted Change language used for keyboard input • Windows Vista Ultimate – Download Language Interface Packs (LIP) through Windows Update • Getting LIP for other Vista editions – Go to Microsoft Web site – See pages 666 -669 97
Summary • Regular preventive maintenance – Improves performance and troubleshooting • Verify Windows settings, defragment hard drives, check drive for errors, reduce startup process to essentials, and free up hard drive space • Windows offers may preventative maintenance tools • Preventative maintenance strategies – Maintain healthy Windows system and hardware resources – Keep good backups of data and system files 98
