Huge File will not Defragment

When I run the disk defragmentor, an abnormally large number of fragmented
(red) files are left.

I checked the log file (see below) and discovered that a single file under
"System Volume Information" was responsible for this.

Can anyone tell me why this is happening or how I might go about fixing it.
The directory name of the file suggests that it is related to system restore
information.

Thanks in advance for any help.

As the file has an extension of .old, I would delete it... or maybe try
renaming it, create a restore point and try a defrag again.

If a file of the same extension refuses to defrag it is a safe bet that
restore creates it as part of it's action.. then I'd delete it and try
again.

If you don't try it it can't go wrong... what's the fun in that ?

If you are not using hibernation the most logical file is the system restore
file which is stored under system volume information.
I always keep an imaged backup of my whole drive just in case of any
problems. Therefore, when i defragment the drive i disable hibernation
(which i use a lot) and i also disable system restore. By disabling system
restore you delete all the restore points that are taking up 12% of your
hard drive. The only sang with disabling system restore is if anything goes
wrong - you have no restore points to restore back to - hence the imaged
backup. As soon as the defragment has finished i then re-enable hibernation
and system restore and also create a new system restore point.
