Intuit Quickbooks Enterprise data files in Windows 7 cannot be opened in Intuit Quickbooks Pro or Premier. Also, Enterprise data files cannot be opened in Intuit Quickbooks for Mac. The main reason to use Intuit Quickbooks Enterprise rather than Pro, Premier, or Mac is the list limits. All versions of Quickbooks other than Enterprise only allow 14,500 names in lists (Customer, Vendor, Items and Employees). If your list size is under these limits, you can safely convert your Intuit Quickbooks Enterprise data file to Pro, Premier, or Mac.
