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 format command given above will create a FAT32 file system. This creates a bootable USB key that can be used for many purposes, once appropriate files are added. For example, it can be used to install Windows 7 (if the flash drive is at least 4 GB and you have a Windows 7 license).
