> It would be very useful to support splitted zip files. I've read
> [https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT] and understood
> that simply concatenating the segments and removing the split signature
> 0x08074b50 from first segment would be sufficient, but it is not that simple
> because compress fails with exception below:
> {code}
> Caused by: java.util.zip.ZipException: archive's ZIP64 end of central
> directory locator is corrupt.
