This may be unique to very large assemblies but it looks like if your file list exceeds 65K items, Excel won't be able to display all the rows.  For example, I just checked out one of my very top level assemblies and there were over 88K warnings - most of them can be ignored, but I usually like to sort the list by warning message so I see that none of them are real problems.  Has anyone else run into and is there a workaround to see the whole file list?  You can save the file list to a .txt file but where can I go from there?
