Great - I understand now and will do as you both suggest. Thanks for your time today!

Hi and thanks for your reply. Defraggler shows it's an SSD. When I analyse, it's b/white, then coloured - mainly blue/orange boxes. I am using "modern view" but if I switch to "original view" then I get the colours in your screenshot. I presume your comments refer to HDD so therefore not to my problem with the SSD?

OK Nergal - thanks. But I did say that previously, I achieved about 5%. Even so, why, after doing a defrag, does it remain at 12%? I appreciate your comments!

I've run Defrag. a couple of times. Today I re-downloaded the program and ran again. The percentage of defragmentation is always 12% - why??? I remember using this program and getting the percentage down to about 5%. Also, I cannot watch the boxes/colours move about the screen (as in the UTube video). I'm trying again and in the Status box (bottom left), the fragmentation says 7% so I thought it was working. Also says 4,000 fragmented files and 29,000 total fragments. At this point (48% optimising) Used Space is 153Gb, Free Space is 54Gb. I know my drive is less than 50% used but I know that the drive "expands" during this process. Now 56% Optimising and 6% Fragmentation. When this process is finished, the numbers will be back to 12% - why? Hope this is enough information.
