I was doing some housekeeping this morning and noticed that I have a folder in my user space inside My Documents called SolidWorks Downloads. Inside this are over 2GB of files inside 3 folders - SolidWorks 2008 SP02/SolidWorks 2008 SP02.1/SolidWorks 2008 SP03.

The question is what are these files and can I safely delete them?
