I have tried to find, what the %SYSTEMDRIVE%\PerfLogs directory is used for. I could only find answers, each differing and none of them have citations.

Since answers, what give file examples on what files are there are in sub-directories, I suspect that there are more undocumented uses for the folder.

I'm looking for an all-inclusive answer on what files may end up in the folder by the Windows 10 system.

Performance Logs

PerfLogs (Performance Logs) is a Windows 7, 8, 8.1 and 10 system generated folder, that stores a log file of system issues and other performance-related reports.

See This And Others using "PerfLogs" in a search at Microsoft.com

When you are prompted to specify the location to save the performance data, you can accept the default location (%systemdrive%\PerfLogs\Admin\<data_collector_set>, and then click Next.

  • I listed the page in my original question. It just says 'it is like that' without any citation. Commented Dec 20, 2019 at 11:00
  • I would edit your answer to that. Though the citation is a partial: It is PerfLogs\Admin, not PerfLogs. Commented Dec 20, 2019 at 11:21
  • @vssher - I have properly cited and quote your reference link. You really should do that yourself in the future.

  • @Ramhound, I will try my best at that, thanks, and I appreciate that you edited it. I am trying to learn how to format in this markdown language. I am only used to HTML for now. I know that's no excuse.
