Plugins
Currently, supports 4.x plugins.
If you select Preferences Web Browsing Netscape Plugins from the K menu you will get a dialog box with two tabbed pages; Scan and Plugins.
The Scan page lets you make scan for new plugins, either manually by pressing the Scan for new plugins button or automatically each time starts up.
The scan is done by looking through the directories listed in the Scan Directories list for .so files containing plugin code. It examines every such file to find out which MIME types the plugin supports. It then creates MIME type definitions for in the user's ~/.kde/share/mimelnk directory to make other applications aware of the new mime types.
The Plugins page shows you the plugins that has found, and for each plugin it lists the MIME types and the filename suffixes it uses to recognise them.
