I have had a problem dumped on me that I cannot resolve. A user |
2 |
archived some very large |
3 |
datasets using Info-zip (app-arch/zip-2.32-r1) and the original data has |
4 |
been deleted. The zip |
5 |
executable is a 64-bit binary and the user assumed that large archives |
6 |
were possible. A typical |
7 |
archive is on the order of 70GB and the largest is over 200GB |
8 |
(compressed sizes). /usr/bin/zip did |
9 |
not complain about creating the archive and /usr/bin/unzip -l lists the |
10 |
contents correctly so the user |
11 |
did not think there were any problems until it came time to extract a |
12 |
file. Extracting any file that |
13 |
is past the 4GB mark in the archive results in a 'bad zipfile offset' |
14 |
error. This is consistent with the |
15 |
FAQ on Info-zip's web site. |
16 |
|
17 |
I am guessing that all of the data is actually present in the zip |
18 |
archives but I cannot get to it. Trying |
19 |
version 3.0 of info-zip or any of the other linux & windows unzip |
20 |
programs has not been successful |
21 |
in extracting any of the later files in the archives. I'm at a loss; |
22 |
does anybody have suggestions on |
23 |
how to retrieve this data? Thanks. |
