Windows File Structure/Paths  Windows XP –User folders stored in path: C:\Documents and Settings\UserName\ –Folders include My Documents, Desktop, Cookies, Start Menu, User Data, and hidden folders. –Folders for user-generated files such as My Music, My Pictures, My Videos, and so on are stored as subfolders of My Documents.  Windows Vista File Structure and Paths –User folders stored in path: C:\Users\UserName\. –Folders such as Documents, Downloads, Favorites, Music, Pictures, Videos, and so on are stored as subfolders of..\UserName\.  Windows 7 File Structure and Paths –User folders and libraries stored in path: C:\Users\UserName\. –Libraries (My Documents, My Music, My Pictures, and My Videos) as well as folders such as Desktop, Download, Favorites, Saved Games and so on are stored as subfolders of..\UserName\.

Windows Command-Line Tools  Taskkill  Shutdown  Tasklist  Make Directory  Remove Directory  Change Directory (MD, RD, CD)  Delete a file (DEL)  Format  Copy  Xcopy  Robocopy  Diskpart  Help

Windows Command-Line Tools  Defrag: Clean up hard drive to get rid of discontiguous files. –From command line, use Defrag. –From Drive Properties sheet  Tools tab  Disk Defragmenter.  NTBackup: To back up folders and files. –Execute from Run line.  CHKDSK.exe: To check the hard disk for physical errors. –Run from the command line. –Drive Properties sheet  Disk Cleanup.  Format: Will prepare a drive to accept data. “Erases” existing data: –Use extra caution when using this tool. –Use “format” from command line. –Right-click My Computer  Manage  Disk Management Console.

Internal Versus External Commands  Internal: When the command line is employed, a series of commands are automatically loaded and available. –Examples: MD, CD, RD, DEL, COPY, ERASE, DIR. –See Table 14-2 for a full list.  External: Must be specifically loaded from the hard drive using the following: –Command line –Start menu –Desktop icons –Examples include Defrag and NTBackup

Windows File Systems  File systems describe the organization of data on a drive –How large files can be –How efficiently data can be stored –How secure the data will be –Access from more than one operating system  Supported Windows File Systems –FAT32 (File Allocation Table 32 bit) –exFAT (FAT64) for 64-bit OS –NTFS (New Technology File System) This is the preferred and default option.

NTFS Features  Access control — Different levels of access control by group, or user can be configured for both folders and individual files.  Built-in compression — Files, folders, or an entire drive can be compressed.  A practical limit for partition sizes of 2TB.  Individual recycle bins for each user.  Support for the Encrypting File System (EFS) — EFS enables data to be stored in an encrypted form. No password; no access to files!  Support for mounting a drive: –Enables you to access a removable-media drive's contents —F or example, as if its contents are stored on your hard disk. –The hard disk's drive letter is used to access data on both the hard disk and the removable media drive.  Disk quota support — The administrator of a system can enforce rules about how much disk space each user is allowed to use for storage.  Hot-swapping — Removable-media drives that have been formatted with NTFS can be connected or removed while the operating system is running.  Indexing —L ocate information quickly when the Search tool is used.

Run-Line Utilities From Start button, select rUn/Search box.  SERVICES.MSC –Views Windows Services  MMC –Microsoft Management Console  Notepad –Opens Notepad text editor  Explorer –Starts Windows Explorer  MSInfo32 –Windows System Information  DXDiag –Starts DirectX Diagnostic  MSConfig –Starts System Configuration utility  Regedit –Launches Registry Editor  CMD –Opens Command Prompt

Folder Management Two methods tomanage folders (directories):  Command Line: –MD = Make Directory. –CD = Change Directory. –RD = Remove Directory.  Windows Explorer/My Computer: –GUI—Point and click management –Right-click in drive/directory space to Create new folder (make directory). Rename a folder. Delete (remove) a folder/file. –Easier navigation using back/forward, up/down pointers in menu bar/navigation bar.

Folder Options Folder Options Access: Access Windows Explorer. Menu bar is hidden by default. To show it temporarily, press Alt+T (which in this case brings up the Tools menu). To show it permanently, click the Organize button, then Layout, and then Menu Bar.

File Management  Similar to folder management: –Right-click to Create, rename, and delete files. New files can be specifically linked to programs installed on the system: –Word, Excel, PowerPoint, and Windows Media Player –Left-click to Open the file (execute it).  System file types: –Binary Example:.exe and.com –Text Example:.bat –.exe,.com., and.bat are examples of file extensions.

File and Folder Attributes  Files can have certain attributes or properties assigned to them. Attributes include –Archive: Indicates whether the file has been archived (that is, backed up). If the archive bit is off, the file does not need to be backed up. If the archive bit is changed, the bit is turned on to indicate that the backup program should include it in the next backup. –Read-only: File cannot be deleted or changed. –System: Cautionary bit to warn against accidental deletion. –Hidden: Causes the file to not appear in the list of files. –Compression: Reduces storage space used by file. –Encryption: Invokes the EFS on the file to restrict access.  Attributes can be changed/modified by –Command line use of attrib command. –In GUI, Windows Explorer, right-click a file to access File Properties. Check/Uncheck the attributes as wanted.

Windows Components: Virtual Memory  Use of hard drive space to substitute for RAM. –Data is sent to hard drive while waiting to be processed by the CPU.  Is only accessed when there are insufficient RAM addresses available to store data in use.  Causes a performance decrease. –Hard drive is much…much slower than RAM.  Use performance monitor to see if RAM is insufficient. Perfmon.exe. Pages consistently near 100% indicate a need for more RAM.  Solution is to add more RAM.

Virtualization Options  Host/Guest Virtualization –PC or workstation runs a standard operating system and a virtualization machine manager (VMM) that runs inside the operating system. –Each virtual machine (VM) is a guest operating system. –Examples Virtual Box: Microsoft Workstation: VMWare  Hypervisor –VMM that runs directly on the hardware, not inside a host OS –Faster than Host/Guest model –Also known as VDI or Virtual Desktop Interface –Examples: Hyper-V: Microsoft ESX/ESXi: VMWare Xen Server: Citrix

Reflection  Amber has just called to tell you that her system is "slow." She restarted it, thinking that would fix it. It worked for a small time, but now it is slow again. –By "slow," she says that the mouse clicks take many seconds to respond, and the Microsoft Word program seems stuck. –Which tool can you use to verify this user's observation and perhaps tell you what is happening?

What Have You Learned? –What are some things to check if the system seems to be slowing down? –What is the difference between an internal command and an external one? –Name two hardware requirements that are different for XP vwersus Vista. –Where would you go to shut down a process/program application that is not responding? –Name two of the files needed to successfully boot XP Vista
