The new version of WinCatalog 2012 (version 3.5.9) which will be released very soon will have a new ability which will help in finding duplicated items.
To start finding duplicates just type a search query as you did previously, click the down arrow on the search button and select “Find Duplicates”. WinCatalog 2012 will run the search but the search results will be grouped by any field (or by a set of fields) by your choice.
To add new grouping rule just drag the column header from the list view control into the grouping area.
This is an example of duplicated items grouped by previously calculated MD5 hash and then by name.
upd: The new version (3.5.9) has been released on March 3rd. You can download it here.
