    File Drag and Drop from dot.net app to external app

    In my application I have a ListView of files that meet certain criteria. I
    have implemented drag/drop from this list to a second ListView of selected
    items. This works well and will accept a filelist from windows explorer.
    Now I want to be able to drag the selected items in the second ListView
    (selected by checkbox) to an external application such as Media Player.

    In my DataObject created to do the drag and drop internally I create an
    array of filenames and use the SetData method with "FileDrop" as the
    DataFormat. This works internally but not externally. When dragged over
    Media Player for example the cursor stays the "blocked" cursor.

    Any ideas?
