Use these settings to specify the options for associating extensions and MIME types with a program so that the appropriate program starts when a user clicks a link. To create a new association, click New. To remove an association, click Delete.
Associations
After you create an association, it appears on this list.
Description
Type the description that you want for this association.
Extensions
Type the extension you want to associate. You should include the period before the extension and a semicolon after the extension. You can include multiple extensions, providing you end each extension with a semicolon (for example, .asf;.asx;).
MIME Type
Type the MIME (Multipurpose Internet Mail Extensions) type to associate with this extension. A MIME type enables a browser to differentiate between different file types using a type designation rather than a file extension.
Command Line
Type the command line or program that you want to execute when a file is opened or a link of this type is clicked. If a script is placed into the <install_dir>/bin folder, you do not need to include path information. You should include the program name, followed by a space, and %1 (for example, netmeeting %1).
