Use the Query List action and filter based on Title contains 'X', and if you want only Folders, or Only documents, or both, then add a filter based on Content Type.
You will then get in return a collection variable will all the matching items.
Thanks for the reply! When I run the query list and put in my filters, nothing is returned. Do I have the correct value for the content type, and if not where would I find that?
Thank you,
Jennifer
Looks correct, but i'm not sure if it is caps sensitive to have documents over Documents. This query will also only look for final within the FileName.
