There are 2 pints in 1 quart, so there will be 3 pints in 1 and 1/2 quarts.
Hi Niki, I understand that Windows Reader is the default Viewer for PDF files. What I was asking was how this was stored in the registry. The key HKEY_CLASSES_ROOT\.pdf key has (Default) = AcroExch.Document (if you have Acrobat Reader installed). In Windows 8 the .pdf key has (Default) =  (blank).
The backup file location on Windows system: On Windows 7/Vista, the file is stored in: \Users\ (username)\AppData\Roaming\Apple Computer\MobileSync\Backup\. On Win XP, the file stored in: \Documents and Settings\ (username)\Application Data\Apple Computer\MobileSync\Backup\.
