Hello brainiacary.



Have you considered installing a 3rd party defrager to see if you get the same results?

I have installed piriform's Defraggler and here is its result :



But Sometimes windows' default disk defragmenter shows it(D drive) as 7% or 8% fragmented but after defragmentation it again goes to 6% and nomatter how many times i try it shows 6%.The fragmentation % does not reduce.

That partition is probably being used by another program. Before defrg, bring up task manger and close all open process in that volume. Additional reasons, below

Why won't some files defrag?

The Defraggler shows D partition to be 0% fragmented but windows shows it 6% fragmented and D partition space is 99% free and i dont think there are anything open.

If you see any fragmentation left over, it's most likely because it's in reserved system space (MFT, System Information volume, pagefile). My guess is Windows cant touch those and correctly reports them fragmented, Defraggler cant touch those either but it doesnt tell you, hence the 0 % fragmentation.

Use the Auslogics Disk Defragger.

I have tried several free and not-free defraggers.

I have settled upon:
  1. Choice #1: contig -q -s c: (or whatever drive you are degragging)
  2. Choice #2: Defraggler because of the graphic display and the indication of which files are involved.
Contig is part of the SysInternals suite. of course, contig can be downloaded separately. Contig is free, is the entire suite. My personal favorites of the suite are autoruns, procmon, proexp.

In a second, I'll get the links you need.

You can not do better than contig in my opinion.

I have no idea what files ar on D but some files are protected and cannot be "defragged". 6% is nothing to be concerned about anyway.

Is there a particular reason this is of concern to you

First off, I agree with zigzag 3143, to wit: 6% is nothing to be concerned about. But that's we not thee.

Windows does, indeed, "lock" some files to which, normally, a defrag will be denied access. I use a free, I think excellent, open source app called UltraDefrag which has the ability to defrag most locked files. You will fine it at SourceForge
