How to use "Unfiled list"

Can you please help me to find out which references I have not jet referred to?

If I open my Endnote, on the left there is a list:

  • All references (59)

  • My document (34)

  • Unfiled (59)

Is it possible to see in that map 'Unfiled" the list of articles are not jet used in my document, instead of all articles that I find now?

Or is the only way to compare the list with all references with the list in my document? How does this folder ‘Unfiled’ eactly work? I could not find this in any help folders.

Thank you for your help!

Thank you very much for your reactions, I’m going to try this.
