Here’s a question from one of our readers,

Looks like my C drive is quite full and around 10 GB of free space are now left in the physical disk. I have just spotted a folder called PerfLogs in my C drive, with just one folder inside it and no visible data. Is it safe to delete it?

Thanks for the question. Let me see if we can clarify this topic for you.



What is the PerfLogs folder in Windows 10 & 7?

PerfLogs (Performance Logs) is a Windows 7 and 10 system generated folder, that stores a log file of system issues and other performance related reports. The folder is typically available in your computer boot partition (typically C:\). It is possible to move / relocate the PerfLogs folder to a new directory, however, from disk space perspective the gains are minimal.

Is it safe to delete the PerfLogs folder?

Although technically possible to remove the folder, that’s not recommended. On a broader sense, we don’t recommend messing with system folders. If you still decide to remove the PerfLogs folder, be aware that Windows will re-create  it every time you delete it. One of the reasons being that Windows features like Reliability Monitor make use of this performance report file to provide detailed performance information.

How much space i will save if i remove PerfLogs?

The folder hardly uses any disk space, so we’d recommend you to leave it as is. If you are looking to optimize your disk space, our first recommendation would be to use the out of the box Disk Cleanup utility. You can launch the cleanup by right clicking your drive partition (C, D and alike), then go to the General tab and hit the b button, Your next step would be to define which files to delete to gain disk space. Typically, downloaded programs and temp internet files would be your first candidates for deletion. Using Disk Cleanup You could also go ahead and delete system files such as Windows Update un-needed files.

How to hide PerfLogs?

If the PerfLogs folder is visible and you it hidden in Windows Explorer, you can simply hide it by right clicking on it and choosing Properties, then in the General  tab, navigate to the Attributes session and select Hide.


And if I don’t have access to the PerfLogs directory?

Access to the operating system files is restricted to administrators; so in case don’t have admin rights on your PC, it’s not likely you’ll have been granted any access to your OS files.

OK, but i still need to cleanup some disk space?

Use a simple tool such as TreeSize Free to analyze your drive and help you find those big hitters that are consuming most of the disk space available. Hint: those are typically the recycle bin contents, browser cache, downloaded files and programs, windows update files and so forth. For sure not the poor PerfLogs folder 😉
