Well the billion byte file for example can not be dragged and
dropped..error will occur. But as stated the usefulness of the file is
limited as the address space must be directly accessed.
The second method does not prevent drag and drop but makes media
duplication much more difficult especially if programmatic calls are
made in the software.
Another method to prevent drag and drop of the file is to remove it from
the TOC. This file can be direct accessed by direct addressing the
location directly however it does not prevent disk duplication, and
standard file access methods that go though the TOC will fail.
I know of no method that would prohibit a legal TOC file from being
dragged and dropped in any of the various CD formats.
