how do I manually uninstall plugin

Hi,
For some reason I’m not able to update this plugin, so I tried to delete it, but I cant. How do I manually delete the plugin? I know I can delete the folder, but I want to make sure there isn’t any other code or anything i need to delete as well.

Thanks for your help!
