How to find nodes which have attachments
To locate nodes containing attachments (inside the entire tree or the selected subtree), first open the tree search dialog (Menu: Search⁄Tree). You can leave the all the fields containing search-terms empty if you wish, then enable the option 'Search nodes containing attachments only' in the 'Search range' tab before you start the search.
If you do not leave the fields containing the search-terms empty, then a search is performed according to the criteria entered but only listing nodes that have attachments.
You can also manually locate a node having attachments by simply browsing the tree: if the selected node has one or more attachments, then the caption of the 'Attachm' button (directly below the article) is in bold.
