Can't delete or rename some files

I've been having trouble with deleting and renaming *some* files for months now. I'm running Windows 10 2OH2.

The problem typically manifests itself in File Explorer. I'll try to delete or rename a file or folder and it usually works but sometimes, it simply won't work. The symptoms are not consistent: sometimes, when I right-click a file and choose delete, absolutely nothing happens. Sometimes, when I try to delete a folder, I get the dialogue that shows it is looking for the files in the folder but it never finds anything, no matter how long I wait. I eventually cancel the dialogue because nothing is happening. When I try to rename a file or folder, it either works or the whole dialogue goes grey and never comes back; eventually, I have to kill File Explorer in Task Manager.

I've tried going old school and simply using DEL commands at the command processor but that doesn't work either. When I tried deleting with the power shell, that failed too. I ran a chkdsk with no flags just to see if the file system was messed up but it didn't find any errors. Also, I installed Unlocker and it is able to delete *some* of the files that File Explorer can't delete but I haven't succeeded in renaming the files that won't rename with File Explorer.

I'd love to fix this problem because I'm accumulating files and folders that I don't want any more. Can anyone suggest a fix?

Hi, try two basic diagnostic steps.
a. Boot to Safe Mode.
Can you then delete one of the 'undeletable' files?

b. Create a new user for test purposes. Log in as that user.
Again, can you then delete one of the 'undeletable' files?

Where are the files located with which you have this problem? If in various locations, is there anything consistent about these?

What types of files are they?
