defrag script for sysinternal contig

This should get you started:

I ran it and got the following:




$LogFile was not created.

Contig.exe is a pre-req. Download it from https://docs.microsoft.com/en-us/sys...wnloads/contig

I'll add a check for that.

I downloaded Contig, ran your script, and got the following:

Why not add the following line to download it?

Code:

IWR -URI 'https://download.sysinternals.com/files/Contig.zip' -OutFile "E:\Testing\Contig.zip"

Then use Expand-Archive to extract the files.

Do you intend to use Optimize-Volume? If not, what will you use?

@Matthew Wai I added a check for Contig.exe on the path and the current folder. Yes, code could be added to download Contig.exe, but then you could argue that the code should also check if the machine is 64bit and run that version if it is. The enhancements may never end. Anyhow, it's not my script. I was just helping @einstein1969 get started. It's up to him now to add further enhancements.

@einstein1969 I'm not sure there is any value in finding the "Allocated Size" values from the command "FSUtil File Layout". Here is the output from Contig and FSUtil for a large file that has 20 fragments:

Maybe you should be looking at the output of "FSUtil File QueryExtents"? This is what I got for the same test file:

In addition to Paul's suggestion, you may use VBScript to run it as an administrator.

Code:

Set l=CreateObject("Shell.Application"):If WScript.Arguments.length=0 Then
l.ShellExecute"wscript.exe",""""&WScript.ScriptFullName&""""&" +","","RunAs",1
Else
Set X=CreateObject("WScript.Shell"):File="E:\Testing.ps1"
X.run("powershell -executionpolicy bypass -File "&""""&File&"""")
End if

Replace "E:\Testing.ps1" with the actual file path. It works as a shortcut.
I have used the same code in the following:
Using CMD script and VBScript to control Windows Update

Hi Matthew, thank you.
She'll meet again after a while. I got busy, but still worked a little bit for that logging problem. When I can continue.

I see that says "Cannot find the specified file". Two possible reasons come to mind:

1. The file was deleted (e.g. temp file) or renamed between the time Contig scanned it and FSUtil was run.

2. There are unusual permissions set on the file that cause it to be seen by Contig, but not by FSUtil.

I added a file existence check in the FSUtill function. That should fix it. If not, let's look closer at the files causing that error.

I updated the ps1 script but I can't find the size of any file on disk C.

Code:

C:\users\All Users\Microsoft\EdgeUpdate\Log\MicrosoftEdgeUpdate.log | 22 | 
C:\users\All Users\Microsoft\Windows\DeviceMetadataCache\dmrc.idx | 4 | 
C:\users\All Users\Microsoft\Windows Security Health\Logs\SHS-07122021-170346-7-7f-19041.1.amd64fre.vb_release.191206-1406.etl | 5 |

C:\users\All Users\USOShared\Logs\System\MoUsoCoreWorker.0349849c-dbcc-40bf-ad8a-651c04d70161.1.etl | 4 |

On the external drive it seems to work instead

Code:

N: \ bck \ backup_macrium \ Version 1809 base \ FABC4503751A17D2-00-00.mrimg | 4 | 48 128 80 11,651,563,520 (10.9 GB) 57,344

For language-dependent strings we can do without it:
You actually need the size allocated only for the stream ::$DATA
it is the fourth value in the section ::$DATA

For some files it does not work in the log I find:

Code:

M: \ Labyrinth - Where Everything Is Possible - Ita_Eng.mkv | 15 | File cannot be found

and it looks like the code page problem I told you.

For reproduce problem try:

- download Victoria 5.36 (Victoria536.zip)
- extract
- found Русский.lng file
- try to fragment:
- for / L% L in (1,1,8) do type Русский.lng >> Русский.lng

- - - Updated - - -

Sorry the error message is:

Code:

M:\Labyrinth - Dove Tutto ╚ Possibile - Ita_Eng.mkv | 15 | File cannot be found

- - - Updated - - -

@all

the 64bit has bug and don't work well, use 32bit version of contig. work well for 32 and 64 bit.

add note that contig64 is broken . Issue #57 . MicrosoftDocs/sysinternals . GitHub

- - - Updated - - -

perhaps version 1.7 ...

Right-click on the Start button --> Windows PowerShell
Run the following command and see whether the size will be displayed.

Code:

Write-Host([math]::round((Get-Item "C:\users\All Users\Microsoft\EdgeUpdate\Log\MicrosoftEdgeUpdate.log").Length/1MB,2))MB

The following is my example output:

Code:

PS C:\Users\Matthew_Wai> Write-Host([math]::round((Get-Item "C:\users\All Users\Microsoft\EdgeUpdate\Log\MicrosoftEdgeUpdate.log").Length/1MB,2))MB

I acknowledge receipt of your PM.
Stack Overflow is a weird site. Previously, it banned me from asking questions there. Recently, it has sent me an email, saying that "Because of recent increases to your Super User reputation, you now have the ability to participate in review queues". It is ironic.

@einstein1969 I finally got the code page problem fixed. I updated the code in my original message.
