Hi all, I hope I am in the correct area for the issue I am having. My laptop is stating that I have used up 647GB out of 680GB but myself & one other have gone through the entire laptop, & the entirety of my laptop does not equal up to the amount in which it says. There is no visible reason as to where my space has gone. I have deleted unwanted/unnecessary programs & files from the control panel, emptied the recycle bin, cleared internet history, I have completed a disc clean up & also a defrag but none of those helped me clear much space. I have tried looking online elsewhere but nothing seems to be working. The same thing is occurring with my 500G external hard drive. All of the items on that add up to 100G but according to properties, I have used over 200G. I am trying to fix both problems but mainly my laptop. Can anybody offer me some assistance? Thanks.
