That isn’t entirely correct as when I defrag partitions, as you get a before and after graphical representation of the partition and you will frequently see gaps in the partition, so no contiguous sorting on mine by default on XP Pro.
For me the windows defrag is very quick, but I have a good CPU enough RAM, a fast SATA 2 HDD which is NTFS file format.
well for me, if i use windows defragmenter and defragment the drive and analyse the disk using defraggler it doesnt give me any spaces … that is it’ll be continuously blue.(to indicate)
+1
Besides, there are 3rd party ones that not only defragment but reorganize and compact.
well i probably didnt get the right words to post then. now tech gave me those right words… reorganize and compact.
i think - generally quick defragmenters use the only defragment option and not the both defragment and compact by default. but windows defragmenter does them both.
edit : if i use full defragment(that is defrag and compact) on defraggler then it takes time. then it’ll be continuously blue(to indicate) but if i use quick defrag then there will be spaces (white blocks) in between files.
Generally, good defragment tools have both options: quick and complete defragmentation 
Defraggler (for free), Diskeeper and PerfectDisk for paid programs.
Wat do u hav to say about AusLogics Disk Defrag?
That’s what I am using myself, but if you are looking for a defragment tool to re-arrange all files and continues your hard drive free-space, it don’t do it
Yes, it is. It defragment quick and fine.
