Windows 10: Cannot delete file it is being used by system!?

I recently downloaded a 4gb file from opensuse.org the intel x86_64 dvd install on my moms computer because my computer broke and i wanted to install it. Now it wouldn't let an administrator delete the file because it is being used by system. AND my mom said today her computer is running slower. shes doing a virus scan now but idk why system would be using a file still. I did try writing the file to a dvd with her dvd writer but it wouldnt work because the writer isn't detected by right click iso burning tool in windows 10. idk why she cant burn files but she has a cd burner. anyways that's w

deleting hard drive files

Hi,

May we know what type of file are you trying to delete? Would it be Office documents, media files, or picture files? If you're trying to delete files for free some space on your device. We suggest to perform a Disc Cleanup. Kindly follow the steps below to
perform the task:

• Type in Cortana Disc Cleanup
  
• Choose the files to delete
  
• Click on "Clean up system files"
  
• Click on Ok
  

For any concerns, don't hesitate to get back to us.

Regards.

 

Unable to delete temporary files

Hi Sumit,

Looks like you are running out of storage space, let's walk you through the steps of running
Disc cleanup for your Windows 10 device.

To delete temporary files, kindly follow these steps:

• Press the Windows key to launch the Start menu.
• Type in Disc cleanup and press Enter.
• Under Files to delete, select the file types to get rid of. To get a description of the file type, select it.
• Select OK.

If you need to free up more space, you can also delete system files:

• Press the Windows key to launch the Start menu.
• Type in Disc cleanup and press Enter.
• In Disk cleanup, select Clean up system files.
• Select the file types to get rid of. To get a description of the file type, select it.
• Select OK.

If the suggestions above didn't work, feel free to post back so we can further troubleshoot.

 

Cannot delete files in Temp

~DF567B.tmp, ~DFB71E.tmp

Those filenames, iirc, I have seen files of that naming nature made by applications created in Visual Basic in the past, & they did not tend to cleanup @ shutdown of the apps that made them.

A list of apps you run @ startup could help us help you understand which apps are creating them possibly, just so you know & then you might be able to find apps that do the same task but do not leave a mess around in your %TEMP%/%TMP% folders.

Also, providing us a list of taskmgr.exe apps via a screenshot of it isn't going to hurt either, just so you understand what may be causing that last filename (~ROMFN_000007A8 )

We're all fairly sure the performance monitoring the system does creates this one though -> Perflib_Perfdata_7a8.dat @ this point.

In any event, I would guess it's apps you run @ system startup, either from the registry RUN areas, &/or startup groups, for the first 3 filenames, mainly because your safemode booting allows you to delete the files & safemode typically doesn't run anything absolutely not necessary to system function (like registry RUN areas & startup group apps).
