Windows有一个内置的日志系统，允许操作系统收集基于性能的日志。这些日志可用于诊断，以了解Windows在不同工作条件下发生的情况。所有这些日志都保存在文件夹中，并且对用户隐藏。在这篇文章中，我们正在查看PerfLogs 文件夹^{(PerfLogs folder)}。

Windows 10 中的 PerfLogs 文件夹

Perflogs 是Performance Logs的缩写，是 Windows 10 存储所有日志文件的操作系统生成的文件夹，其中包括系统问题、与性能相关的报告。和其他对分析有用的矩阵。该文件夹位于安装操作系统的根目录 (% SYSTEMDRIVE %PerfLogs) 中，但处于隐藏状态，需要管理员权限才能访问。

如果您想以一种可以理解的方式阅读这些文件，那么您需要使用Windows 10中提供的性能监视器工具^{(Performance Monitor tool)}。该工具还从PerfLogs中提取日志文件并提供更好的视图。您还可以使用此工具运行诊断。

• 在开始^(Start)菜单中，键入并打开性能监视器^{(Performance Monitor)}
• Expand Data Collectors Sets > User Defined并右键单击它
• Select New > Data Collector Set。按照向导进行操作，您可以从预定义的模板中进行选择

完成后，开始数据收集，它将立即开始捕获将存储在PerfLogs文件夹中的数据。如果您在文件夹内手动移动，您将在以下路径中找到日志。

C:\PerfLogs\System\Diagnostics\<Data Collector Set Name>\ComputerName_Date-000001

文件夹中有一个Reports.html文件，您可以在任何浏览器中打开该文件，并以易于理解和可视的格式查看性能日志文件的摘要。

PerfLogs文件夹可以^(PerfLogs)安全删除吗？

这些只是日志文件，因此您可以自由删除该文件夹，而且它是安全的。但是，每次删除文件夹时，操作系统都会自动生成它。如果日志文件占用太多时间，您可以删除它们以腾出空间，但如果您经常遇到问题，那么最好重新定位该文件夹。

就我们所见，重定位并不完全奏效，Windows仍然可以生成PerfLogs文件夹。最好将文件夹保持原样，并且只保存较小的文本文件是无害的。

我希望您能够了解Perflogs文件夹。

What is PerfLogs folder in Windows 10

Windows has a built-in logging system that allows the OS to collect a рerformance-based log. These logs are usеful for diagnosis to find out what іs going on with Windows under different working condіtions. All these logs are kept into folders and are hidden from users. In this post, we arе lookіng at the PerfLogs folder.

PerfLogs folder in Windows 10

Perflogs, short for Performance Logs, is an OS generated folder where Windows 10 stores all log files, which includes system issues, performance-related reports. And other matrics useful for analysis. The folder is located in the root directory (%SYSTEMDRIVE%\PerfLogs) where the OS is installed, but is hidden, and needs admin permission to access it.

If you want to read these files in a way it can be understood, then you need to use the Performance Monitor tool that is available in Windows 10. The tool also picks up log files from the PerfLogs and gives a better view. You can also run your diagnostics using this tool.

• In the Start menu, type, and open Performance Monitor
• Expand Data Collectors Sets > User Defined and right-click on it
• Select New > Data Collector Set. Follow the wizard, and you can choose from a predefined template

Once done, start the data collection, it will instantly start capturing data that will be stored in the PerfLogs folder. If you manually move inside the folder, you will find the logs on the following path.

C:\PerfLogs\System\Diagnostics\<Data Collector Set Name>\ComputerName_Date-000001

There is a Reports.html file inside the folder which you can open in any browser and look at the summary of performance logs file in an understandable and visual format.

Is the PerfLogs folder safe to delete?

These only log files, and hence you are free to delete the folder, and it’s safe. However, every time you delete the folder, it will be autogenerated by the OS.  If the log files are taking too much time, you can delete them to clear space, but if you are facing the problem often, then it is best to relocate the folder.

To what we have seen, relocating doesn’t work completely, and Windows can still generate the PerfLogs folder. It would be best to leave the folder as is, and it’s harmless with only holds text files that are small in size.

I hope you were able to understand about Perflogs folder.
