Hello Davey,
Thanks for your reply. I've seen the new RC2, downloaded and used it instead of the older release. Now the new program 'only' used approx 9 hours to finish for a 500 Gb drive. From the graffic I can see it's working better now: filling up more white space during the normal defrag run. RC2 also leaves less red area's, still some red are displayed together with light blue blocks spread over the white area. What I can't see now in RC2 is the file that is worked on. Probably better not, to avoid a lot of discussions. After completion I have seen the Pc is closing down much quicker then before. An automatic powerdown option of the Pc after completion would be an item on my wishlist.
What I do is run CCleaner first, select the drive in Defraggler, Analyze, and hit the Defrag button. What I've done in earlier releases is defrag after analyze the drive and thereafter defrag the empty space. Running Windows Vista.
I will start RC2 now running the defrag of free space. Local time here is 10:00.
