Deleting converted backup?

I have successfully upgraded to ver.4 and used the backup and convert method. Now that I know it is working properly- I would like to delete the backup file and am unsure which file I can remove. I have a winvista.pvm and a winvista.hdd. Is one of those files the backup or do I have another file I should be looking at? My laptop drive is getting tight on space and I have no reason to keep two large files on the drive.

 

I was wondering the same thing. Did you ever get a response to this in some other way than here?
