Need to delete sales log

Hi, I can’t figure out how to delete my entire sales history in wordpress e-commerce. I know how to delete some of by going to Dashboard -> Store Sales. But I can only delete 1 page at a time. And I have many, many pages to delete, so that would be tedious and take forever.

So, can someone tell me where to locate the file or files that holds all my customer purchase data please so I can delete it all at once? I’m paranoid about a break in and someone stealing customers sensitive info.

Thanks!
