        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.
