Prevent indexing of certain file types

Enabling this policy allows you to edit the list of file types to exclude from indexing. The end user cannot modify this list. You should separate each extension type with a semicolon. Note that limitations of Group Policy Object Editor require this list to be split across multiple values. Desktop Search combines all these into a single exclusion list. When this policy is disabled or not configured the user can edit the default list of excluded file types. If you enable and then disable this policy the user’s original list is restored. If you want to specify an initial default list of excluded file types that users can change later see the administration guide for information about how to set up the initial machine preference.

Stop indexing in the event of limited hard drive space

Enabling this policy prevents indexing from continuing after less than the specified amount of hard drive space is left on the same drive as the index location. Select between 0 and 2147483647 MB. Enable this policy if computers in your environment have extremely limited hard drive space. When this policy is disabled or not configured Windows Desktop Search automatically manages your index size.

Prevent indexing certain paths

If you enable this policy setting you specify a list of paths to exclude from indexing. The user cannot enter any path that starts with one of the paths you specified. If you enable and then disable this policy setting users can index any path not restricted by other policies but their original list of paths to index is not restored.
