(Works with all Windows versions)
There are a lot of temporary files on your hard drive that Windows puts there when performing various tasks, but never gets around to deleting. Considerately, Windows does provide a function to delete these and other space-taking files: Disk Clean Up.
To run Disk Clean Up, double-click your “My Computer” icon (or click the Start button and then choose Computer from the pop-up menu) and then right click your “C Drive” folder. Click on “Properties” and you’ll see a pie chart and stats on your hard drive, and some tabs at the top.
Go to the “General Tab” and then click on “Disk Cleanup.” This will scan your computer for available space and then present you with another dialogue box. Here you can view the files that are currently available to be deleted without causing problems on your system. These types of files include: Recycle Bin, Temporary Internet Files, and the ability to compress your older files.
You can click on each item and view a brief description of what its purpose and reason is for being on your system. If it says, “You can safely delete these files,” check mark these items. The other items you will have to use your own discretion, because once they are deleted, they are gone. After check marking the files you want to delete, click on “Clean Up.”
