For Drag&Drop, this series of articles are a great point to start. After I understood that the files must have the flag can copy, can move, etc. I had almost the solution. The magic was to add one line in GetAttributesOf:

*rgfInOut |= SFGAO_CANCOPY|SFGAO_CANMOVE;

Also I had to publish the IDataObject in GetUIObjectOf like this:

if(riid == IID_IDataObject) {
    PWSTR pszName;
    hr = _GetName(apidl[0], &pszName);
    hr = SHCreateDataObject(m_pidl, cidl, apidl,
                            new CFileDataObject(pszName), riid, ppv);
} else if(riid == IID_IDropTarget) {
    // TODO publish
    return E_NOINTERFACE;
}

That's all.

By the way what is the best practice for allocating CFileDataObject here?
