Giant Disk Cleaner is a robust program especially designed to clear unwanted and unnecessary files from your computer recovering valuable hard disk space and boosting your PC’s performance. While some files are necessary for your system to run properly others are useless and take up valuable hard drive space, jeopardizing your computer’s performance.

Windows applications create and place several temporary files on your computer. When an application terminates it should remove these obsolete/junk files but often times these files remain on your computer for various reasons such as program errors, sloppy architecture or improper system shutdown. Many applications also add folders and shortcuts to your Desktop and Start menu during their installation process.

This poses no real threat to your system but when you remove a program by deleting it in the program directory, these files are often overlooked.
