Windows 10: PfPre mkd file not showing on Prefetch folder.

So I found an issue with the PfPre file on Prefetch folder. On the Prefetch folder, the PfPre MKD file is not showing. I delete the contents of the Prefetch folder for freeing up space. I tried going to services and restarted SysMain, but it did it again. How do I fix this issue? Thanks in advance!

Cannot delete .mkd file in prefetch

The PfPre_******.mkd files are system files used by prefetch/SuperFetch.

While SuperFetch and prefetch can be stopped/disabled, this is only recommended in some cases when a solid state drive is used.

The best general recommendation is just to leave these files and the entire prefetch folder alone.

 

Cannot delete .mkd file in prefetch

Hi Antony and thank you for the support.

If you have read my first post in this thread, you will notice that I had already performed a clean boot and a safe boot.

Nevertheless, I tried the clean boot option again.

I couldn't delete the .mkd file in prefetch.

I proceeded to stop all the services I mentioned in my first post of this thread - the services which are using this .mkd file.

After stopping them all until the last one, superfetch, I was able to delete the file. And so I did.

Then, upon starting these services, the file reappeared in prefetch.

You stated that third party software was causing this file to remain undeletable.

If this was the case, then I should have been able to delete it when I performed a clean boot.

Is it normal to have files in prefetch that cannot be deleted or modified? Or, again I ask you, is it a symptom of a hacked PC?

Thanks!

 

PfPre_405196c1.mkd file

This file is in my prefetch folder and can never be deleted. It is dated the same day I "upgraded" to windows 10 . Does anyone know what this file is and what application the .mkd file extension might be coming from ? I looked online and there is very little
about the .mkd extension . I never had file in prefetch that could not be deleted under any circumstance. One site stated that the .MKD is from persuasive SQL. Please any information

This is not the only post about this particular file on the Microsoft support site. There are no solutions posted that I can find
