Why does Defraggler take so many hours to defragment as opposed to Window’s defragment tool?

Defraggler
1

When I defragment using the program included with Windows (“Defragment and Optimize Drives”), it takes 1–5 minutes to defragment, but when I use Piriform’s Defraggler, which I downloaded yesterday, it takes many hours to defragment.

Why is this?

Also, I haven’t tried the “quick defragment” option yet. What is the difference between defragment and quick defragment?

G'day Papi and welcome tot he forum,

what OS are you running?

what is the size of your drive?

what sort of drive, SSD or HDD?

when using Piriform's DF. what options are you using?, just the default settings?

here's an explanation of DF's quick defrag; http://www.piriform.com/docs/defraggler/defraggler-settings/defraggler-options-quick-defrag

I am using Windows 10. No matter which drive I defragment, it is significantly slower than if I defragment it with Window’s defragment tool.

Does Defraggler do a more in-depth fragment than Window’s built-in tool?

I was hoping you'd say your drives are SSD's and DF was seeing them as HDD and doing a full defrag whereas Windows defragger was seeing them properly and just optimising them (doing a Trim).

so, what type of drives have you used DF and Windows defragger on?

what are their capacities?

are they all internal drives?

is there a difference in the type of defragging you get DF to do as opposed the the sort Windows defragger is doing?

also, in DF, make sure the Stop VSS option is ticked, you'll find it in Settings, Options, Advanced.

Its probably Defraggler's defrag algorithm which makes it so slow, although it does consolidate/fill gaps very well at the cost of speed.

Also the defrag tool in Win10 will only defrag files up to a certain file size: 64MB

Supposedly there's a way around that by instead defragmenting via a command prompt although you will likely loose Restore Points doing so.

what the...? there is?

What does this option do? What does “VSS” mean?

If that’s the case, that explains why Defraggler takes a much longer time to defragment the files than Window’s drive optimization tool does. I have a lot of files over 64 MB.

a bit of documentation here on VSS; http://www.piriform.com/docs/defraggler/defraggler-settings/defraggler-options-advanced-tab

I'll let you use Google to fill in any other blanks. :)
