I noticed something remarkable in DF v2.11. After DF has come up with a list file that are defragged (including the folder directory files) and I click on "Size"to let them be sorted on size then something remarkable happens. DF applies the sorting of the files seperately on the directory files and all other files. So, I got a list with all the directories at the top sorted by size and below that a list with all the other files sorted by size. See attachment.
I am not critizising it. I appreciate it. Thumbs up for the developers.
