Encrypt/decript large files

[Eric Harlow]

Encrypting small files is no problem.  However, when I
try to encrypt/decrypt a large database backup on
Win2k, it appears to encrypt fine - but it's hard to
tell since when I try to decrypt the file, I get an
error.  The original file is slightly over 6 gigabytes
and will probably grow in time.  I've tried this
several different ways - symmetric keys, with and
without the --armor option and they all seem to give
me basically the same error.

C:\gpg>gpg --decrypt test2.asc > decrypt.avi
