When you filter library content using one of the
  Documents or Tags browsing
  views, it is not possible to tell where an item or folder resides within the
  library folder structure. The Locate File and
  Locate Folder actions reveal the actual location of
  an item or folder in the library.
    This task assumes you are in the library of the desired site and a
    Documents view (All Documents, I'm Editing, Others
    are Editing, Recently Modified, Recently Added, or My Favorites) or
    Tag view is selected in the browsing pane. To view
    the location of a folder the Show Folders feature
    must be enabled.
    - In the item list position the cursor over the item or folder of interest to display the available actions.
 - Depending on the type of content you have selected, click Locate File, or click More and then Locate Folder.
 
The page updates to display the selected folder or item as it
    exists in the library. The Library tree in the browsing pane shows the
    current location, as does the breadcrumb path at the top of the
    page.
