I recently improved my Zip classes for Xojo so that they can read zip files that are created by Finder (or by Apple’s “ditto” tool) and are over 4 GB in size.
Most unzip apps, including the ones on macOS and Linux, can’t unzip these, but my code can, now.
It may even be able to write them back out, but I haven’t tested that thoroughly, yet (you’re welcome to try and report back to me).
I have not released that new version, yet, because, well, it’s not too well tested, but it did well enough for the recent need I made it for.
Is there anyone here who uses my code and needs this? And would do some more testing? Then get in contact, please, or comment here.
