I use Subversion/SVN for source code control and that uses several hidden folders and files on my drive to maintain SCC status - it'd be nice if V I Analyzer ignored these files. In fact, maybe it's a bug - it analyzes the files,even when they have the odd SVN extensions. For example: if you have a VI under source code control:
c:\testercode\test.vi
then you'll end up with another file that SVN creates:
c:\testcode\test\.svn\text-base\text.vi.svn-base
Although it doesn't have a valid LabVIEW extension, V I Analyzer loads and analyzes this file.
