Subject Re: [compress] create 7zip archive
Date Thu, 06 Jun 2013 11:46:35 GMT
Multi-volume - I have figured it out already :-(
I need to transfer 150+ MB files to our service provider and a transfer time is out of transaction
length. The provider accepts multivolume zip/7z as well, but there is no java / unix support
to chunk these archives. 7z format can be easily binary split, zip cannot.
Spec - I started to create an HTML page, so I can at least use links to jump between each
definition. Could you please contact me with Damjan him to verify my findings? I will post
the result, if it will be worth of.

Well, I don't expect us to support everything either.  We don't support
multiple volumes in the zip package, for example.

Kudos to Damjan who figured things out for us, but I recall him saying
something similar about the quality of "the spec".
