Recently I have come across with a  common problem that most of the users  facing , “suddenly my hard disk is full how I can find out  which file or folder taking more space ?”

As an administrator I can say  that there are several tools you can use to identify your  hard disk space usage of file or folders, Among that my favorite  tool is  WinDirStat, , it’s a  nice tool to find out and show you where and which file is occupying more space on your hard disk by visual image ,

 http://windirstat.info/download.html it's a free and open source software 

just give a try and let us know whats ur oppnion . :)
