A user archived some very large datasets using Info-zip (app-arch/zip-2.32-r1) and the original data has been deleted. The zip executable is a 64-bit binary and the user assumed that large archives were possible. A typical archive is on the order of 70GB and the largest is over 200GB (compressed sizes). /usr/bin/zip did not complain about creating the archive and /usr/bin/unzip -l lists the contents correctly so the user did not think there were any problems until it came time to extract a file. Extracting any file that is past the 4GB mark in the archive results in a 'bad zipfile offset' error. This is consistent with the FAQ on Info-zip's web site. I am guessing that all of the data is actually present in the zip archives but I cannot get to it. Trying version 3.0 of info-zip or any of the other linux & windows unzip programs has not been successful in extracting any of the later files in the archives. I'm at a loss; does anybody have suggestions on how to retrieve this data? Thanks. Doug -- Douglas O'Neal Manager, Bioinformatics Core Center Delaware Biotechnology Institute
