How to add a path filter to views 3 in Drupal 7?
Try the Views URL alias module.

The 'Views URL alias' module allows Views to be filtered by path aliases.
This module is useful if your website uses heirachical paths. It allows you to filter and sort a view by URL aliases. When combined with the Views bulk operation (VBO) module you can apply operations to a specific section of your website based on a URL alias.

Note that Currently, only node aliases are supported.
