Subject [jira] [Commented] (COMPRESS-465) Unexpected record signature: 0X6F4A2D4E
Date Fri, 21 Sep 2018 15:42:00 GMT


Stefan Bodewig commented on COMPRESS-465:

A first experiment shows that {{ZipFile}} can read the archive, so at least you've got a workaround.
The archive uses data descriptors for stored entries so pretty much all bets are off as soon
as something that vaguely looks like a ZIP file is contained inside of the archive as a nested
archive. I haven't fully identified whether the "archive in archive" pattern is throwing off
{{ZipArchiveInputStream}}, though.

> Hi,
> Commons compress is not recognizing all entries from zip files downloaded from
cloud, when you choose to download several files as a zip archive. Others archivers like 7zip
and Windows Explorer are able to read all zip content. Example attached.
