path
Background
A very powerful feature of Drupal is the ability to have control over all paths. The path module is the tool that provides this functionality and is part of the basic Drupal installation, although it is not enabled by default. Some examples of re-mapping paths are:

user/login => login

image/tid/16 => store

taxonomy/term/7+19+20+21 => store/products/whirlygigs

node/3 => contact
This functionality integrates seamlessly into node forms and also provides the administrator an interface to view all aliases that have been created.

Aliases have a many to one relationship with their original Drupal URLs. In other words you can have many different aliases map to a single path. An example of where a multiple aliases come in handy is creating a standard RSS feed URL:

node/feed => rss.xml
node/feed => index.rdf
When Drupal generates links for a path with multiple aliases it will choose the first alias created per system URL. So in our above example, Drupal would use rss.xml as the default alias rather than index.rdf. To change this behavior, delete the aliases for node/feed and create the index.rdf alias before rss.xml.

path - Allows users to rename URLs.
