Optimize and Defrag Drives in Windows 10  

Hello @Underthaker,

I just had a quick look for you but there doesn't seem to be an option for output . . .

Code:

Get-Help Optimize-Volume -Full

Is it possible to use this command "Optimize-Volume -DriveLetter C -Verbose" but creating the report file type (.txt)? Something like this:
Optimize-Volume -DriveLetter C -Verbose | Out-File -Filepath "Optimize-VolumeSystemDrive.txt" using powershell command or script (.ps1)?

The command will run defrag, will not cause an error & will create an empty output file.

I don't know what you want to keep defrag records for but if doing so is important to you then use the cmd version instead of PS e.g.

Code:

defrag.exe C: -O -H >"F:\Wherever\Defrag.Log"

defrag - TenForumsTutorials
Defrag - SS64
defrag - MSDocs (MSLearn)


Thanks for the rep,
Denis

Hello @Brink,

There are a few new switch parameters to OPTION TWO - To Optimize Drives in Command Prompt that could now be added to the parameters list.

If documented, they should show up if you run defrag in CMD Prompt.

Code:

Switch	Description

/F      Forces defragmentation of the volume when free space is low.
/R      Performs partial defragmentation (default).
        Attempts to consolidate only fragments smaller than 64 megabytes (MB).
/W      Performs full defragmentation. 
        Attempts to consolidate all file fragments, regardless of their files & fragments size.

I hope this helps.

Thank you Paul. Where did you see this from?

I'm not seeing the new parameters listed in the command prompt.

Apologies @Brink,

On investigation, this appears to be Win 7 related.

The strange thing is, that although those command line commands are valid, they do NOT show in the Win 7 list either. Here is just one site I looked at > Free to Defragment Hard Drive with Command Prompt or Powershell

No apologies needed. Makes you wonder why it's not in any reference material from Microsoft unless deprecated.

I think those were Vista switches.
See What does this defrag switch do - TechNet

I've seen them mentioned before but whether it was here or SevenForums I do not remember.
I never saw any report that anybody had tried them and that they had any real effect in Ten or in Seven.

The 64MB limit was added to defrag with the advent of Windows 7 so it became redundant then. That /r switch in Vista indicates that it had been added earlier as an experiment.
