Thanks
I use pagedefrag for some time now, and just love sysinternal tools in general. But pagedefrag has a fixed list of files to defrag.
I've just upgraded to the new version of Defraggler, and the interactive map (good improvement, BTW) shows me that... it's not files that have spread, as isolated blue squares (see attcht) display "no files are in the block" : so, what ? NTFS internal structures ? directory entries ?
FYI : 16.7GB partition, 2GB pagefile, defragged and freespace-defragged
