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).
Prior to Windows Vista, a file in the Recycle Bin is stored in its physical location and renamed as D<original drive letter of file><#>.<original extension>. A hidden file called info2 (info in Windows 95 without the Windows Desktop Update) stores the file's original path and original name in binary format.
