While you’re working with Windows or surfing online, your computer generates temporary files or other junk data. To keep it running at top performance, you should regularly clear out your hard drive. Glary Disk Cleaner makes doing so easy. Unlike the built-in Disk Cleanup utility in Windows, Glary Disk Cleaner displays detailed scan results, enabling you to choose individual files to be deleted. You can also use the tool to get rid of outdated Windows Update data.
