How to Find Out What Is Using Your Drive Space

by Cameron Easey

Every time you download a file, save a file or install a program on your computer, you are using space on the hard drive. If your hard drive is getting full, you may want to see how much space various files and installed programs use on the hard drive. You can do this by viewing the size of installed programs from the Control Panel. You can also use a program, such as TreeSize, to see the amount of space used for all of the files and folders on your system.

Add and Remove Programs List


Click on the "Start" menu and then go to the "Control Panel."


Double click the "Add or Remove Programs" icon.


Wait for the Currently Installed Programs list to load.


Scroll down through the list to see the amount of space each installed program takes up on the hard drive. It will be marked "size."



Download and install the TreeSize program to your system. Save the file to your desktop and then double click the downloaded file to install the program.


Double click the TreeSize icon on the desktop to open the program.


Wait while the program analyzes your hard drive and displays the amount of space used by files and folders.
