> 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.
