This short tutorial applies to anyone using windows XP or windows 2000. We are always inclined to let our computers pile up with junk and think that all we have to do is just turn it on and off each day expecting it to run like a well oiled machine. Truth is that you computer each day accumulates a lot of junk files and can even accumulate damaged sectors as a result of such junk files. Every time you go onto the internet, create a new file, use your music and of course download those essential files, depending on what you consider essential your PC is building up all the remnants of such files unknown to the vast majority of us. As part of your "keep my computer tidy effort", we are going to look at how we can clean off such files. [Running the Cleanup utility] Step 1. Launch Disk Cleanup via "Start menu. Step 2. Arrow down to Programs menu. Step 3. Arrow down to Accessories Step 4. Arrow down to System Tools and right arrow in here. Step 5. Arrow down to "disk cleanup" and press the enter key. Note: A dialogue window will appear enabling you to select the drive you want to clean up. In this case it will always be "Local drive C:" as this is where our windows operating system resides and so does all other files related to anything we do within the environment of windows for our day to day work. Step 6. Arrow up or down in the list box to Select the required drive and then tab to the OK. Button and press the spacebar Note: The process begins of windows examining The specified drive, and the amount of space you can potentially free up calculated. This scanning can take a few minutes or seconds depending on your system and how fast it is so give it time and the results will come up where then jaws will announce what is on the screen. Part 2. (Select Files) Step 1. Tab to the list of file categories. Each of these items in the list presented to you is preceded by a checkbox which can be checked or unchecked using the spacebar. Note: As you arrow through this list you will be told where the files are coming from that are presented to you in the list, for example; * Temporary files. * Temporary Internet files. * Cache files. * backup files. Note: The above list is just an example and your list may differ slightly. Step 2.Check the boxes associated with the items you want to delete and click OK. Note: I have personally checked all the boxes in this list, some of them are checked already and if you wish to exercise caution then just leave what is checked by default and continue to next step. Step 3. Tab to the ok button and hit the spacebar, you may or may not be asked if you are sure you wish to delete the items that have been marked for deletion, just answer "yes or ok" to this prompt by using the tab key and spacebar. When the job is finished, tab to the "ok or close button" and press the spacebar to finish off. Well done, you have performed a disk cleanup. ******************************************************************** NOTICE: The information contained in this email and any attachments is confidential and may be privileged.
