    XceedZip 6.0.6275 creating corrupt multi-volume Zip64 files?

    A client is using this older version of the library. When we try to uncompress these spanned files, we get the warning that we are not licensed to read or create Zip64 archives, although a huge multi-volume archive already exists. I downloaded a trial of the latest version to use that key for them, and am currently in progress of attempting to extract (it's around 40 gigs!), but even the UnzipPreprocessingFile/64 event is only being fired 65535 times. 

    I assume, since the licensing said Zip64 was unsupported when uncompressing, that it is also unsupported when compressing. But now I'm stuck trying to figure out what the rest of that data is, if it really fails after 65535 files. We'll see if the uncompression with the later version works or not.

    Has anyone else run into a similar issue?

    Replying to myself. Turns out the data is all in the stream with proper local file headers and file data sections. It's just the central directory that is truncated. I ended up writing something to parse through and extract everything without using the central directory.
