Windows disk space explained - “Where Did My Space Go?” by Robert Mitchell

“I have a 250GB hard drive. When I look at the properties of the drive, it tells me that I have 75GB free and that 175GB are in use. However, when I add all my files together, I only see 150GB in use. That is a difference of 25GB. Where did my space go?”

Ever have a similar question in your mind?  Sure you do.  Robert explains many of the mysteries in the blog post at  Nicely done Robert.
