I have a intel solid state drive that is being used as the system drive (c:). The drive is aboutr two years old. It has lost about 10 GB of memory over a period of time. I have seen nortons av temp files grow on other pc in the past but don't see that happening with any files on the c drive on this pc. I have installed recently the treesize application and it hasn't shown any files that have changed dramatically in size. Report is attached. I have also turned off the page file and then started it back on again, and yes I gained a little but not much. I have run dskchk / f. ANY idea's what could be eating space?
