Organize & SafeguardYour Hard Drive By Alberta Rouse
Your Hard Drive • The hard disk/drive of your computer is where all programs and data are stored. • The hard disk is the most important kind of permanent storage used in PCs. • Others being floppy disks, CD-ROMs, DVDs, tapes, removable drives, etc.
Amazing Facts Hard disk drives have progressed dramatically in the last 20 years. • The first PC hard disks had: • 10 MB capacity • Cost over $100 per MB • Modern hard disks have: • Capacities of 100s of GBs • Cost less than 1 cent per MB! • This is a 1,000,000% in just under 20 years, or around 67% cumulative improvement per year. • At the same time, the speed of the hard disk and its interfaces have increased dramatically as well.

Your hard disk plays a major role in the following important aspects of your computer system: • Performance: The hard disk plays a very important role in overall system performance. The speed at which the PC boots up and programs load is directly related to hard disk speed. • Storage Capacity: A bigger hard disk allows you to store more programs and data. • Reliability: Determine how important a hardware item is by considering how much grief is caused when/if it fails. Therefore, the hard disk is the most important component by a long shot—hardware can be replaced, but data cannot. A good quality hard disk, combined with smart maintenance and backup habits, can help ensure that the nightmare of data loss doesn't happen to you.
Basic Terms File Each document is a file and would include a plain text file, a letter in Word, digital music, a spreadsheet, a digital picture or directions/code for a program.

Creating a New FileManagement System Windows uses a filing system that is very similar to a paper filing system and is organized using Windows Explorer or My Computer features. To open Windows Explorer, Right Click the Start Button and select Explore.
Windows Explorer • One of the best tools that Microsoft has created to assist computer users. • Explorer consists of two windows: • Left Window-lists all of the drives & directories on your computer • Right Window-shows the contents of those drives & directories
Storage on the Hard Drive • The files are stored in the folders and subfolders. • The folders and subfolders are similar to the file folders in a file cabinet.
The Address Bar at the top tells you where you are at in the hard drive. • C: or the letter followed by a colon is the drive you are looking at. • The first name after C:\ is the directory or folder where you are. • Any other names behind that are subdirectories. A subdirectory is a directory that is stored in another directory.
Creating a New Folder • With Windows Explorer open. • Click to select the folder or drive in which you want to create a new folder. • Click File/New/Folder. • Type a name for the new folder, and then press Enter.
Changing the Name of a File or Folder • In My Computer or Windows Explorer, right click on the file or folder you want to rename. • Select rename from the list. • Type the new name, and press Enter. Tip: A file name can contain up to 255 characters, including spaces, but it cannot contain any of the following characters: \ / : * ? “ < > |
Copying a File or Folder • In My Computer or Windows Explorer, right click & drag the file or folder to where you want to copy. • Select Copy here from the list.
Moving a File or Folder • In My Computer or Windows Explorer, right click and drag the file or folder you want to move to the place you want to move it. • Select Move Here from the list.
Deleting a File or Folder • In My Computer or Windows Explorer, locate the file or folder you wish to delete. • Right Click the file or folder. • Select Delete and click yes.
File Information • If you hover your mouse pointer over a file name, some information about that file will be shown. • If you right click the file and choose properties, you can find further information about it. • This can be useful if you see a file and don’t know what it is or where it came from.
File Extensions • Files have what are called “extensions,” or three-letter designations after the main name. • For example, in the file bear.gif , .gif is the extension. This extension indicates that this file is a picture.
Common File Extensions .doc = a Microsoft Word Document .txt = a text file .pdf = an Adobe Acrobat file .wps = a Microsoft works spreadsheet .gif = a picture file .jpeg = a picture file .bmp = a picture file .zip = a compressed file
Finding a File or Folder • Right click the Start button, and choose Search • Click All Files and Folders. • In the name box, type all or part of the file’s name. • If you do not know the name of a file or want to refine the search, click the Date Modified, Size, or Advanced options. • If you want to specify where Windows should begin its search, use the Look In drop down menu. • Click Search.
Backup & Maintenance • Finally, it is no fun to lose work, files, hard disk, etc. A backup strategy must be in place to safeguard important files/documents. • Use Windows backup feature. Search Help, print and follow the Help directions. • Or Save the files to a floppy disk, CD-ROM, another computer on network, flash drive, etc. • Internet email such as Gmail, Yahoo, Hotmail can also provide you with an offsite place to save important files/documents.
