free program for cleaning PC memory

Freeing disk space is always a great way to speed up your PCs functions, but how do you figure out which program/file is hogging all your memory space? If you have been looking for an effective software to help you with this, WinDirStat is your best solution. WinDirStat is based on the Linux application KDirStat. Both programs offer you a visual display of your memory space and hard drive. It allows you to identify which programs take up too much space, consequently slowing down your PC. It also provides a clean up option if you want to fix the problem right away.
