That file is in a format from a program by the name of XPSLara and it's far from a standard format so you're not likely to find other software than can open the file. My suggestion would be to download the program and convert it to something else. What I've found suggests the Wavefront (.obj) file format can be exported to.
Uh... have you tried searching the internet for the answer to this question?
