     Length comparison is a very good check. However, exact length
information for the original file is rarely available from http download
sites (or any download site under the browsers I've used).

     Exact file length information is available from ftp sites accessed via a
good ftp program; but, downloads done this way in binary mode are very seldom
corrupted anyway.

     Don't know how often this may be a problem. 2MG format sounds like one
which would normally be recognized as a PC binary type.
