I'm on V6R1 and I'm zipping via QShell using an old version of the zip

first then FTP them to a Windows Server where I join them back together
after unzipping them.

I've heard that JDK 1.7 supports unlimited sizes when compressing via the
jar command. I have confirmed that JDK1.7 on Windows successfully extracts
large files from a jar file but my i5/OS is V6R1 and it appears that JDK1.7
is not supported until V7R1.

I've also read that more recent versions of gzip use ustar headers that
support at least 8Gb. However, my file is 80Gb so does anyone know of a
version of gzip that does not suffer from a size limit and if so, where can
I get a binary version that can run directly on i5.

I thought I had cracked it by writing an RPGLE that writes a large file to
STDOUT and then used QShell system command to call the program and pipe it
into the zip command. This appeared to result in the entire large file
being zipped but the Windows machine failed because it found a mismatch
between size attributes stored in the zip file.

Any other ideas would be appreciated.

Peter
