        On all my windows 10 computers, the C:\Users\Computer_Name\AppData\Local\Temp folder gets filled with a bunch of 0 KB files named for example “mat-debug-2384.log”. I’ve searched the internet from one end to the other and have not found the solution to what is creating all these files and how do I stop them. Please, there has to be an expert here that can answer this.

        Mine started appearing after installing KB4549951 on May 5 on W10 1909.
        There is 1 file for each day except for 2 files in May 7 which had ChrEdge update.

        Aria…log seems to be connected with Telemtry, but no one at Microsoft knows what Aria and Mat debug files are :

        The xxxxx is the PID number creating the .log file.

        Here I found, that is due to incorrect OneDrive setup. So my thought is, that mat-debug is releated to other application/service that is running into issues.

        I don’t use OneDrive.

        @tom-gorman my bet is on OneDrive, or some sort of MS Office mutation.

        Is there any non-zero size file? Mine contains some info..

        Looking at the time of mat-debug creation I looked at event-viewer log and found Event-ID 0 for ChrEdge updates.

        Use disk cleanup to rid them. ie
        cmd.exe /c Cleanmgr /sageset:65535 & Cleanmgr /sagerun:65535

        be sure Cleanmgr is allowed folder access via the ‘Protected Folders” in ‘Widows Security” under ‘RansomeWare Protecton’

        🍻

        Just because you don't know where you are going doesn't mean any road will get you there.

        When i try to delete it, it says it’s part of ‘XboxAppServices’

        PS.

        I should also note that I don’t allow Onedrive to get access to my folders via Windows Security Options. I never use Onedrive for anything. The only reason that I don’t Uninstall Onedrive is because MS will cause problems in future updates if I do.

        MS are as incompetent as they are greedy. With Win 10 it feels like my own PC does not belong to me anymore, strange because I don’t remember MS buying it for me.

        It is caused by MS with their retarded updates and zero quality control. This bug has been going on for years. MS don’t care and don’t respond to people asking about it. MS solution, take the money and ignore the customer after.

        Took me a long time to find an answer to this problem.
        The problem is a MS update that messes up Onedrive & MS Office along with other MS apps.

        In the link below you only need to read the posts by Richspacenuke. Ignore Ghost363, you don’t need to un/install anything and, unknown 3rd party software is risky for this kind of procedure. Win 10 has the tools you need. I suggest reading all 7 pages, it is short.

        >>> Never delete files when you are tired or distracted. <<<

        If you don’t know, and to help other readers find what they need :
        You can open Command Prompt via Win Key + r then type cmd (there are several ways to open the Command Prompt including the Control Panel and the Start Menu/Windows System folder). Then you type msconfig for the Boot Options as described further below.

        To get to the 2 Temp Directories, press and hold the Win Key and the r key (should open Run) then type temp (or) Win Key + r then type %temp% to get to the other temp directory (for aria debug 0kb files). Quite ironic that the files are called “debug files”.

        You can get to Disc Clean Up via the Start Menu (Windows Admin Folder) or, you can Right Click the Mouse over the C Drive, click on Properties, it should open on the General tab, you will see a button for Disc Clean Up on that tab (next to the circle representing hard disc space). That will take you to the Check Box Options page.
        >> Read the descriptions for each Check Box Option by highlighting any of the box options via the left mouse click.<<

        https://answers.microsoft.com/en-us/windows/forum/all/mat-debug-xxxxlog-files/8875d070-62f9-429b-b3e1-9a6e006c45be?page=2

        “The FIX that has worked so far is this: I ran msconfig, checked boot option box as “Safe Mode”, and checked “minimum”, then restarted the computer into Safe Mode and ran Disk Clean Up, then looked in temp file (found no files in my Temp folder, having cleaned them out before I restarted) and confirmed there were no files. Then I unchecked Boot from Safe Mode and Rebooted back into normal windows 10. Viola! no more mat-debug files! This beats uninstalling and reinstalling stuff!”

        (he did not mention that %temp% is also creating aria debug 0kb files. You can get to this directory via Win + r then type %temp%)

        He then mentions the Check Boxes that he selected in the Disk Clean up options :

        “The only reason I can see the FIX works (still holding true after 5-6 shutdowns and startups of my laptop) is that I ran Disk Clean in Safe Mode and the Safe Mode configuration released files from active use that were deleted by that action, uniquely. All I know, is that it worked. If you want I can give you the boxes that I checked in using MS Disk Cleaner. Of course I also uninstalled One Drive and assured that Smartbyte Telemetry was disabled thoroughly before I ran in Safe Mode.”
        >>(again, you don’t need to un/instal anything)<<

        >>> (important that you learn what these options do. If you click on the options you will be given a description. Some files you want to clean up but, others you want to leave alone. careful which check boxes you want to select for deletion.) <<< ….

        Check Boxes to select :
        “Yes. First delete the existing files in my temp folder and run Cleanmgr once before going to Safe Mode. Make sure that it is checked to clean out all temporary files, temporary internet files, thumbnails, recycle bin files, and delivery optimization files.
        Also, I would delete browsing history including using Internet Options and cookies under Control Panel. ”

        You may also have old MS Windows Update Files in the GB size range that are safe to remove.
        I hope this fixes your MS buggy update issues, it can easily happen again in the future so take notes here for future reference.

        I remember when computers did not have all this nonsense, they have trashed it. Now they just want your money for nothing.

        >>> My next PC is going to be a Linux OS <<<

        Did you see this thread? mat-debug-xxxx.log files – Microsoft Community

        I solved the annoying problem with mat-debug-xxxx.log files for me using the commands:

         

        Get-AppxProvisionedPackage -Online | Where-Object {$_.PackageName -Like “Microsoft.MicrosoftOfficeHub”} | ForEach-Object { Remove-AppxProvisionedPackage -Online -PackageName $_.PackageName}

         

        Get-AppxPackage Microsoft.MicrosoftOfficeHub | Remove-AppxPackage

         

        See: https://docs.microsoft.com/en-us/windows/privacy/manage-connections-from-windows-operating-system-components-to-microsoft-services

         

        In my case the files in tmp folder were created by the program:
        C:\Program Files\WindowsApps\Microsoft.MicrosoftOfficeHub_18.2005.1191.0_x64__8wekyb3d8bbwe\LocalBridge.exe
        Found by Sysinternals’ Procmon.”
