4. Extensions section

App Uninstaller scans Extensions in user and system folders right after being started and finds 8 types of extensions.

  • Launch Agents – hidden or background programs that run on user login or system startup. App Uninstaller displays agents that are stored in the current user and system folders. You can disable the agents’ autolaunch or delete the launch agents from the disk.
  • Login Items – user-facing programs that run on user login. The app displays a list of installed applications that have special agents and you can disable their autolaunch. You can also manage login items accessible through System Preferences.
  • Installations – files that are used to set up programs. There is a list of installation files stored on the Startup Disk. You can remove unneeded files to clean up disk space.
  • Web Browser Extensions – plugins that extend your browser with additional services and modify web pages.
  • Screen Savers – programs that fill the screen when the computer is not in use. App Uninstaller displays installed screen savers and allows you to remove them.
  • Preference Panes – special dynamically loaded plugins to customize working of some installed services or applications. The app displays installed Preference Panes and allows you to remove them completely with their service files.
  • Internet Plugins – program components that add specific features for Internet browsing. Please be careful when you remove system plugins because it may harm the working of the system.
  • Widgets – simple and easy-to-use programs launched by the Dashboard app.  Please be careful when you remove core widgets because they do not operate independently but can only be installed with the system.
