Okay ....... I've gone into "My Computer", right clicked the C Drive, selected properties and it confirms 18gb drive with 17gb used up.
My issue now is with 17gb used up ...... I don't have a huge amount of software on board and I'm struggling to find evidence to back up 17gb used !
Is there a quick and easy way to check folder sizes, without having to open up each one and check the individual file sizes ?
