am using an acer laptop ( aspire ) windows 7 with 500 G.b hard the hard is not divided , it's only C and am really organized there is is one folder called gus where i put every thing dvided into folders inside it the rest of the laptop is empty that folder is almost 70 G.b , but the used space in my hard is about 156 G.b knowing that i don't have any games and i have 2 CAD programs and adobe pro extend which are about 5 G.b is it possible that the standard programs take that much space ? i've only seen that problem in windows 7

Gus, I could go thru the standard advice of running Disk Cleanup, decreasing the amount of space used for System Restore Points, turning off hibernate if you don't use it, BUT I suspect you are really after an easy way of determining what is using how much space Microsoft doesn't provide an easy and/or graphical way to do what you would like which is why I use WinDirStat , http://windirstat.info/index.php

To check the size of Program folders - open Windows Explorer, navigate to the Program Files folder, right click on the folders and select Properties. It will show the total size of the folder.
