Did not expect unzip to still have 4G limit... the website that was used to share the photos creates the zip file on the fly. I see there is zip64 https://sourceforge.net/projects/zip64file/ (GPLv2)
Thank you for the last pointer (sorry to have left you). Given that unzip has its 4Gb limit - fair enough - and that p7zip should do the bigger job, this bug could have be closed. But I found this useful post: "The basic Zip format has a limit of 4 GB per file. You need to upgrade your zip tool to one that supports Zip64: $ zip -v Zip special compilation options: ZIP64_SUPPORT (use Zip64 to store large files in archives) Alternatively, use a different archive format such as 7z or tar." Similarly, $ unzip -v UnZip special compilation options: ZIP64_SUPPORT (archives using Zip64 for large files supported) From your link: "Zip64File is a JAVA library which implements the 64-bit extension of the ZIP standard from PKWARE using random-access, permitting to access archives larger than 4 GB with more than 65 K files." So it appears that with this library, and the ZIP64_SUPPORT compile option, this might be correctable. Assigning globally.
