The .OXPS file type refers to the open XPS file format. This is one of the new file formats introduced after the launch of microsoft's windows 8 platform. The full name of the file is Open XML Paper specification.

The .OXPS and .xps are two more popular and growing file formats that compete with the PDF file format for fixed document description. The .OXPS file is not natively supported by the previous versions of windows. The main advantage of .OXPS is the ability for device independance and resolution independance. The file's structure is natively based on XML.
