A utility included with Microsoft Windows 98 that helps you reclaim space on your hard drive by deleting files you no longer need.
You can use Disk Cleanup to select the types of files to uninstall and to inspect and remove files in the Recycle Bin, temporary files, Internet cache files, and unneeded Microsoft ActiveX components.
You can also use Disk Cleanup to remove optional Windows components that you no longer need, remove programs that you installed, and convert a FAT16 partition to FAT32
You can configure Disk Cleanup to automatically run when your disk is low on space.
