We have a lot of InfoPath forms deployed on our SharePoint 2013 farm as custom Content Types. Over the period of time there are now a lot of such unused custom content types in gallery. When i say a lot of, i mean around 60-80 in count.
I have to delete these unused content types to make the environment cleaner. I know that i can go to content type gallery and start deleting individual content types. But, i don't want to repeat the steps 70-80 times. So, i am looking for some trick to do this quickly, if possible.
Thanks in advance.
