Appearance
This message is sent to the caller of DrgDragFiles to tell it to render a file.

Remarks
This message is sent when DRF_USER is specified in DrgDragFiles. The receiver should perform the operation indicated by the TRUE field in the RENDERFILE structure, moving or copying hstrSource to hstrTarget.
When the operation is complete, a DM_FILERENDERED message should be sent to hwndDragFiles window.
The RENDERFILE structure is allocated temporarily for the receiver of this message. The receiver should make a copy if it needs to use the data in this structure after returning.
Default Processing
The WinDefWindowProc function does not expect to receive this message and takes no action other than to return 0.
