Home Forums Mac Software Mac Applications Can size of Calendars and Reminders be decreased?

I made the folder named TRASHME and moved a Calendar and Reminders file into it, but that only created a duplicate Calendar and Reminders file in TRASHME while the original file remained in the Applications Folder next to Calendar.app. How do I prevent the duplicate from being made?

I'm using Yosemite 10.10.2.
