Whenever I save even a blank part, file size says 0KB. I've tried saving as different names and in different locations. I have also tried opening an existing model and saving that as a different name and in different locations, but the same thing happens. When I try to open that "part," SolidWorks just says error opening part contact Tech Support for possible solutions.  Asking the Forum before I contact my VAR.
