Why are there no colours apart from grey and some red? For some strange reason Mydefrag does not show any other colours and moves the gray bars all around.
By the way, JKdefrag 3.36 works perfectly well and shows all the colours on the same computer.
Maybe because on average your files are not fragmented? What do you think yourself? The yellow lines signify fragmented files, the greyish blue area consists of unfragmented files, the red lines are unmovable and the black means empty space. Whta colors would you have wanted more?
