Why? I'm not asking you, Tim, I just wonder why one would they invent their own dialect of an existing format? The stream indetifier is a 14 bytes and the checksum is a few bytes per chunk that are actually helpful. > I've opened: > https://issues.apache.org/jira/browse/COMPRESS-352 Thanks, I'll answer over there.

And the internet has answers...according to http://fileformats.archiveteam.org/wiki/IWA "However, the variant of Snappy that is used does not comply with the spec for that format, omitting the stream identifier and checksum." I've opened: https://issues.apache.org/jira/browse/COMPRESS-352 -Original Message- From: Allison, Timothy B.

All, Over on Tika, we recently had a user post some new Apple iWorks files. These are zips that now contain mostly .iwa files. I found one mention on the internet that these might be snappy compressed, but I'm not having luck opening them. I get only -1 with SNAPPY_RAW, and I get an exception with SNAPPY_FRAMED. The files are posted on our jira [0]. Any recommendations? Thank you.
