Windows 10: defrag script for sysinternal contig

Hi, I'm writing a batch for defrag file with the sysinternal contig. I need a hand to develop and test it better. For now it performs only the analysis and is developed for the "Italian" language but I would like to make it more flexible. Code: :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :: By :: :: Ver 0.0.2 12/07/2021 :: :: You need download sysinternal contig (32bit) and copy in "windows\system32" folder :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: @Echo off setlocal enabledelayedexpansion set "Disk=N" rem italian set "string1=Dimensioni allocate" chcp 1252 echo Analyze the files. set f=0 for /f "tokens=*" %%F in ('contig -a -s "!Disk!:\*.*" ^| find "fragments"') do ( call set "s=%%F" set "s=!s:*...=!" set "s=!s:~0,-10!" for %%A in ("!s: =\!") do set "fr=%%~nA" if not defined fr echo [!s!] Error in frags number. & pause & goto :eof set "$=!fr!fedcba9876543210" set/a l=0x!$:~16,1!+1, f+=1 for %%A in ("!l!") do set "fn=!s:~,-%%~A!" set "fn=!fn:~,-7!" if not exist "!fn!" echo [!fn!] Error, file not found. & pause & goto :eof for %%A in ("!fn!") do set "t=%%~aA" if not defined t echo [!fn!] [!fr!] Error in attributes. & pause & goto :eof if "!t:~0,1!"=="d" (set "t=d") else set "t=f" set "dim=" if "!t!"=="f" ( for /f "tokens=4" %%d in ('fsutil file layout "!fn!" ^| find "!string1!"') do if not defined dim set "dim=%%d" set "dim=!dim:.=!" ) else set "dim=0" echo [!f!] [type=!t!] [File_name=!fn!] [Frags=!fr!] [Dim=!dim!] ) pause goto :eof :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: EDIT: update script to version 0.0.2, fixed an error on retrive allocate dimension of file

Apparent bug in SysInternals Contig v1.8

I can't find a SysInternals forum online. If this is not the right place to post this, please direct me elsewhere.

There is an apparent bug in Contig v1.8. In some cases, "contig -s -v <filespec>" will not use the last block of free space on a volume. In other cases, it will. I've seen both behaviors on the same machine, but I can't explain when it happens and when
it doesn't. I've been unable to defrag a file even though there is a huge amount of free space at the end of the volume.

In this case, there was no other I/O in process to the volume (not the system volume) that could explain another task reserving the extent.

Case 1 - "contig -s -v" does not use the last block of free space on the volume. Volume is FAT-32.

In this case, the free space extent at the end of the volume was used when defragmenting.

So the behavior appears to be inconsistent. Note that, in both cases, the largest extent of free space was at the end of the volume.

　

　

　

 

Windows 10 won't defrag

It looks like there's some files and folders it doesn't want to touch. In cases like this on a traditional hard disk, I recommend using

Sysinternals' Contig utility which ensures that files are contiguous (all one piece, not fragmented).

• Navigate to the above link and download the ZIP file and extract it to a location of your choice.
• Open an Administrator Command Prompt window like before, and navigate to where the folder is located.
• Run contig.exe /s /v C:\*.* (You may be prompted to accept the EULA first).
• You'll see a lot of stuff scroll across the screen indicating file name, fragments before, and fragments after, and finally a summary at the end.

Copy and paste the summary at the end for reference and check the disk defragmenter again after running contig.exe, the amount of fragmented space should be lower.

 

How to Remove Sysinternals Live?


I mistakenly downloaded and installed Sysinternals Live instead of only Autoruns.

I've looked through my list of installed programs but I don't see SysInternals Live.

Can anyone suggest a method by which I can remove SystInternals Live from my PC?

Thank you.
