Mainplatz
A free tool called MeinPlatz can look at your hard drives and folders to find empty space or space that isn't being used.
When you pick the plate you need to break down, the program will show you a rundown of the relative multitude of envelopes with the space each takes up (generally Records and Program Documents take up the vast majority of your hard circle). You should simply right-click on one of them to rehash the interaction, this time with an emphasis on an envelope.
This way you can see where there is the best convergence of consumed space on your PC, and where you have free space.
MeinPlatz is an easy-to-use program that lets you quickly look through your computer records.
