Hi there, @ptla. 

I'm here to help you restore your company file. 

QuickBooks Desktop uses different types of files to store different types of data.  That said, you can search for the  file extension file type and delete the necessary files that you don't need.

Please refer to this article to see different information on how QuickBooks Desktop uses different types of files to store different types of data: File types and extensions used by QuickBooks Desktop.

If you're unable to see the file extension, you can change the folder and search options on the folder and uncheck the box in Hide extensions for known file types to distinguish the extension file type.

Please follow these steps:

1. Go to the containing folder (C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files) and select View on the menu.
2. Click Options and then select Change folder and search options.
   
3. Select View and then uncheck Hide extensions for known files.
4. Click Apply and hit OK.
   
   There it will show the extension file type and quickly trace the file to delete it.
   
   

I'll add some articles as your reference in creating a company file without starting from scratch:

• Create a new company file from an existing one.
• Rename your QuickBooks Desktop company file.
