This module helps you find views that use a given content type in Drupal 6.
It is useful when you are making modifications to a content type and want to see which views it may affect.
Installing:
Install the module as normal. Navigate to administer >> build >> modules. Enable Viewfinder. The menu item should then appear under Admin > Views > Viewfinder.
Contributions: it would be great to have this tool find views based on various other criteria
