There are four different exclude sections at the moment:

Product excludes

This section lists all products defined internally and in the external include files. If you want to exclude a complete product, or include it again, select the file from this section and toggle the checkbox before the product.

Cookie excludes

Cookies are usage tracks, but you may want to keep some useful cookies. This section lists all cookies currently on your system, allowing you to exclude them from further searches.
(At the moment, only Internet Explorer and Netscape Navigator cookies are supported û Opera cookies can only be deleted completely)

Extension excludes

This is about the common Windows file open dialog. It saves lists of opened (and saved) files divided into extensions. If you donét want to remove the WinWord files, for example, you could select .doc to be excluded in this section.

Single excludes

If you do not want to exclude a complete product, but only a single file or registry setting of it, you can select that one from the results list. These are listed here, where you may remove them from the exclude list again.

All the lists in these sections have a context menu with extended selection options.

You can find the exclude settings by choosing a category from the Excludes section in the toolbar to the left.
