[How many times do you defrag to defrag a file]

I defrag eavey day but when I check the file list the same file keeps appearing day after day so how many times does it take to defrag a file.

Is there a way to do a complete defrag in one go?

[After defraging still loads of red squares]

I have been defraging my notebook for three days now it started off at 44.0GB - 8159Files - 24310 Fragments. Now it is at 8 files and 511 fragments. The display pane is split in two, top half solid blue but there is still loads of area at the bottom red, as if showing many fragments. By the way it still shows 23.6GB fragment. Any Ideas?

[Not finishing the defrag]

Each time I defrag it never finishes the process as per attachment. What do I need to do get it to finish?
