Date: Thu, 24 Jun 2004 03:19:34 -0700 [thread overview]
Message-ID: <BAY17-F24AlDCVrvGAk00075c7b@hotmail.com> (raw)
DVDs with 2-4GB files get their filesizes truncated. Are there even
"cruft" CDs in circulation today? Maybe it should be a config item.
A popular competing os seems to handle 2-4GB isofs filesizes.
