ZIP64 File Format Clarification
I assume in order to use zip64 for larger files, I would need to be using a 64 bit machine? If so, this will not work as many of our clients use 32 bit machines. What are my other options?
Chilkat Zip supports the ZIP64 file extensions. If a zip is too large (more than 4GB), either in whole or because of the number of files zipped (> 65536), then the ZIP64 extensions are automatically used. The 64-bit Zip file format extensions may be used on both 32-bit and 64-bit operating systems. The ZIP64 extensions only apply to the Zip file format, not the operating system.
