If your folders are alphabetically named, then you should be able to narrow down the search by using "D" in the "Folder name" slot.
Then search on that folder and you will find it somewhere in the list alongside those that contain D, bit not at the start. "Send", for example, will be after the D hits.
Then, if you also have the "Folder path" slot visible, you will see where the D folder sits in the hierarchy.
If these columns are not visible, right click the columns slot at the top, where it offers to sort your hits, and go to the "Columns" slot and add them.
