I'm trying to clean up an assembly, and I'm not have much luck. I can see several "file not found" in the references, but they're old files that are not needed. Can I find where these files are reference, and remove that? Searching and Goto didn't find anything. Also, when I close the main assembly file, I have all sorts of other files that somehow got loaded. I don't even know how to do this, since none of the files we have here at work do this.
