For a variety of reasons, our org's content is a bit messy, and I would like to clean it up. Specifically, I have things in my own My Content which I would like to delete, but to be safe, I want to confirm that no Web Maps/Applications are referencing them.
The first thing is to ditch items which are not shared. After that, though, I can't think of a way to determine which group's maps use what services without tons and tons of clicking. Is there a way to produce a list/report/matrix to help me along? Can I select a bunch of Web Maps and generate a list of all content which they collectively reference?
