Excel file deletion
 

I cannot delete an old excel file cached on C drive because get message
"Cannot delete solver: access is denied"

The files are read only and this seems to be the problem

The folder has multiplied to 50 levels and Norton will not scan it. Norton
stopped scanning because of this. I have added the files to the Norton
exclusiuons but want to delete the excel folder(s). THis has enabled me to do
a manyal scan of the C drive.

How do I delete it?
