partition Defrag

[Dstar]

After analizing my partitioned drive (D, the result was that the available
space is 6% where most of the used space needs to be defragged. When I
clicked Dfragment, the message I got was that in order for it to defragment
the drive, it needs 15% space available, otherwise it won't work properly.
Do I still want to do it. P.S., I should also delete files.

Well, upon doing a disk clean up on this drive, I was told that this is
impossible since this is a backup drive and a cleanup is dangerous.

Can I safeley defrag this drive without any damage?

Please clarify:

What is your D drive? In other words - is this something you created or was
it there before you got there? What is stored on it?

The D drive is the partitioned recovery drive. The computer came this way.

If it is your recovery 'drive' - you should not touch it. It is not
affecting your performance.

Dstar,
Although defrag says that 15% free space is required for
defragmentation process, this is an optimum.

Disk Defragmenter will run (forced) and though it may not be as
efficient nor be able to actually defragment as many files, it will
certainly not do any harm.

Disk Defragmenter says that it needs this 15% free space to run because
of the possibility that you have a few files of a significant size on
the disk or partition.

It needs the free space to sort the file out into a single block - the
less free space you have on the drive - the smaller the files it can
successfully sort out.

This doesn't mean that the process cannot be completed with less than
15% free space, if the files are small enough.

But the figure of 15% is a mean average of file sizes to the room needed
to sort them.

The other side of this is that if you have many very large files on your
drive, then 20% free space will not be enough space for the process to
sort out the largest of these files.

But, as you can see, it is just a matter of space to move the file
fragments around in order to join them up - or not (not enough space).
There is no issue of 'damage' or 'danger' here. It either succeeds
totally or is unable to defragment some of the larger files.

The more free space the better - irrespective of the 15% mark.
