You need to override OnDrop() in your CListCtrl derived class and provide a COleDataSource.

You need to hook up LVN_BEGINDRAG to detect the beginning of a drag drop and then call DoDragDrop with an IDataObject based data source populated with the file information (easiest format to handle is CF_HDROP). The Windows shell handles everything else.

Fortunately much of the leg work has already been done for you in the MFC class COleDataSource. There are also some great examples available:
