If you have a .zip file containing plugins/features releated to the plugin to be installed. You can copy and paste plugins and features to [MyEclipse installation dir]/dropins. (If you don’t have folders named plugins/features, it is recommended that you create them under dropins and copy and paste relevant plugins/features to their respective folders)
