Autodesk Inventor

Hello everyone,

I was given a flashdrive with a ton of Inventor parts (.ipt) and assemblies (.iam). I'm using Solidworks 2013, and i can not figure out how to get these files to open. I can't get them in a new file type so i just need a way to get them open as is. I believe they were made on Inventor 2011 if that helps. Any help would be very appreciated!
