Why does HD look like this after defrag?

[Bender Blues]

Always used just W10 defrag, heard good things about Defraggler - thought I'd give it a go.

1tb/7200

After clearing all OS cache, temps, browser, history etc and reboot.

 

Ran analyze (%23) then "defrag" - said time remaining 1 day and change. I guess this is a Defraggler thing in length of time.

Ran quick defrag, and completed. I'm not concerned about remaining fragmented files (deal with later)-

Its the scattering fragments and empty spaces.

 

Why would it be left like this? W10 defrag says 0% fragmented after running Defraggler.

Maybe that's as good as it gets?

It's probably ignoring larger files, especially if you're doing a quick defrag. There's less benefit in moving large files since access time on one large file isn't as bad as accessing thousands of small files. It doesn't really matter where something like a 2GB video file is located.

I haven't used it in years but if you check the settings in defraggler it'll likely have an option for what size files to ignore.

Great point, that makes really good sense. Windirstat - yeah, theres some beefy ones, I'll check out that max size, as a matter of fact I remember seeing it so it is indeed there.

Thanks Spotty!

 

edit: theres a great description of quick, size exclusions and exactly what ya pointed out.

Take care.

Some defrag problems also have an option to leave a bit of empty space after files as sort of futureproofing for when they grow later.

And since you're already checking the drive, you can always move stuff onto another drive and back. Moving the big file onto it should put it into the next clean block. Sort of a extra tedious manual defrag that needs two drives.
