I recently checked how much free space I had remaining on my "C" drive and found that I only had 9.68GB left out of a total capacity of 222GB. I ran Windows Disk Defragmenter but after 18 hours it was still running so I cancelled it. On re-checking my hard drive I found to my amazement that I now had 42.8GB of free space! I then downloaded the free Auslogics disk defragmenter and ran that. It completed in a few minutes and showed that the Windows defrag had done most of the work but for some reason had failed to finish.
I am very surprised that the process of defragging freed up so much space. On consulting various forums, most peoples' experience seems to have been the exact opposite. The common consensus seems to be that defragging reduces the amount of free space on a disk rather than increasing it. Why was my experience so different?
I suspect it may be because I had used up too much of my free space than I should have. I was down to just over 4% before I defragged. Was that too little? How much free space should I leave unused to ensure my pc is running properly?
I would be grateful for any assistance that members of this forum can give me.
