    I would like to make a Zip64 archive from a bunch of files (bzip2 files, specifically, but it shouldn't matter), using 7za's -so option to send the compressed archive to standard output: 

    $ 7za a dummy -tzip -so myFiles*.bz2 -mx0 > test.zip

    Here is the output: 

    7-Zip (A) [64] 9.13 beta  Copyright (c) 1999-2010 Igor Pavlov  2010-04-15
p7zip Version 9.13 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,2 CPUs)
Scanning

E_NOINTERFACE

    The file test.zip is empty. I cannot find mention in the documentation about the error E_NOINTERFACE or what it means. What can I do within the application to fix this? Thanks for your advice!

    There two version of standard output ZIP
    1) PKWare version from standard appnote. But  PKZip doesn't use it. And maybe noone use it (I don't know)
    2) InfoZip's version.
    The problem that these version are not compatible.
    So any choice from them is not good.
    So 7-Zip doesn't support creating zip to standard output.

    I'll fix error message.
