Free Up Space on Your Hard Disk
- As you use your computer, the Windows operating system creates many additional files that you probably don't know about and probably don't need. These include:
- Downloaded Program Files - Files that accompanied a download but are not necessary for the operation of the downloaded program
- Temporary Internet Files - Whenever you visit a page on the World Wide Web, your browser saves a copy of the page on the assumption that you may want to see it again and it can be retrieved faster from your hard drive than by having to go back out to the Internet to get it. Over time you can accumulate hundreds of megabytes of such files -- all of which are unnecessary.
- Back-up Files - Many programs, such as word processors, routinely save a copy of your document as a safety measure in case of a computer crash. These back-up copies are no longer needed after you have saved the file in the regular way.
- Log Files - These are files that are created by many programs to provide you with a record of what they have done. In some instances such a record is useful in determining why a program failed or why a particular error message appeared, but in most cases they are simply records of information that you will never need.
- Other Temporary Files - Temporary files are created for a variety of purposes. After you have finished the task they are no longer needed.
- Files in the Recyle Bin - When you delete a file it is sent to the Recycle Bin. It stays there until you delete it from that location or until you have deleted so many files that the Bin can no longer hold them all, in which case the oldest files in the Bin are deleted. The only reason to keep a file in the Recycle Bin is if you find that you deleted it in error and want to restore it.
- These files not only take up unnecessary space on your hard drive, their mere presence can slow down the operation of your computer
- To get rid of them
- Click on "Start"
- Hover your mouse pointer over "All Programs"
- Move up and hover your mouse pointer over "Accessories"
- Move right and down and hover your mouse pointer over "System Tools"
- Move right and down and Left-Click on "Disk Cleanup"
- A Disk Cleanup dialog box will open and the program will check your hard drive for unneeded files (this may take a while if you haven't done it for a while [or ever!])
- When the process is complete, a Disk Cleanup for Drive C:\ dialog box will open. It will display the amount of space currently being taken up by each of the categories of unneeded files and will have a check mark before each of the category labels.
- If there is a category that you don't want to delete, click on the box to un-check it.
- Otherwise, click "OK" to delete the unneeded files.
- It is a good idea to do this at least once every week or so
Rearrange Items on your Hard Disk to make your Programs Run Faster
- Fragmentation refers to the condition of a disk in which files are divided into pieces scattered around the disk. Fragmentation occurs naturally when you use a disk frequently: creating, deleting and modifying files. At some point, the operating system needs to store parts of a file in noncontinguous clusters. This is entirely invisible to the user, but it can slow down the speed at which data is accessed because the disk drive must search through different parts of the disk to put together a single file.
- To speed up your computer, you can perform an operation called "Defragmentation" or, more commonly, "Defragging"
- Before defragging it is important to shut down all running programs, especially anti-virus programs and screen savers. This is necessary because, if during the process a program should attempt to access a file on the drive that is being defragmented, the process has to be started all over again.
- In theory, firewalls should also be shut down, but in my opinion, the risk of opening your system to the outside world is greater than the risk of having the defragmentation process restarted
- To defrag your hard drive:
- Click on "Start"
- Hover your mouse pointer over "All Programs"
- Move up and hover your mouse pointer over "Accessories"
- Move right and down and hover your mouse pointer over "System Tools"
- Move right and down and Left-Click on "Disk Defragmenter"
- When the "Disk Defragmenter" window opens you'll see a list of the hard drives displayed at the top of the screen. Left-Click to select the drive you want to defragment (usually Drive C:/), then click on the "Analyze" button
- The Estimated Disk Usage Before Defragmentation and Estimated Disk Usage After Defragmentation will be displayed on the Analysis Report.
- A new window opens with a brief recommendation of what action Disk Defragmenter thinks should be taken regarding the chosen drive. It's important to note that this is just a recommendation based on the percentage of fragmented files to total files and doesn't prevent the drive from being defragmented if you feel it needs to be done and might improve system performance.
- If you want to go ahead and defragment without more information, Left-Click the "Defragment" button. or if the recommendation is that defragmentation is not needed, Left-Click the "Close" button
- Clicking the "View Report" will provide you with a great deal more information about your hard drive, but typically this is not needed to successfully accomplish defragging.
- After the defragmentation process completes, clicking the "View Report" button will bring up the Defragmentation Report. It takes the exact same form as the Analysis Report, but shows the post defragmentation results.
- It is a good idea to do this at least once a month
