Why link icon during drag and drop to iTunes target?
During drag and drop of an MP4 video file from Windows 7 PC to iTunes library, it shows a link icon, not the icon for the file. Likewise during drag and drop of a PDF file from my PC to an app within iTunes that supports that (like GoodReader), it also shows a link icon, not the icon for the file. The link icon says "link" with a symbolic arrow, indicating the actual file isn't being copied, rather a link back to the file.
However in both cases the actual file (not a link) IS copied to iTunes and if the device is sync'd, transferred to the device.
When using the CTRL or SHIFT key to modify the drag/drop operation from copy to move, the iTunes UI doesn't respond but maintains the link icon. ALT key during drag/drop causes the icon to become a copy icon with "copy" and plus sign, but it does the same thing as the link icon -- file is copied.
Is this expected behavior or a bug?
