GB PKSFX size 2 GB PKSFX Patch size 2 GB Actual archive size depends on available storage space the theoretical limit is 9 EB Actual number of files may vary depending on available memory and resources The theoretical limit is actually 4 G but the practical limit for most current system configurations is about 262 144 files 24 PKZIP 6 0 Command Line Getting Started Manual Your available system resources and system settings limit the performance you can expect from PKZIP when processing large numbers of files or large archives If you are compressing large numbers of files on a computer with insufficient memory you can expect slow or possibly incomplete processing if your available memory is depleted When compressing large files it is a good idea to make sure you have your temporary folder set to a location on a drive with sufficient disk space available to process large files It is currently not recommended to use Drag and Drop with very large files or with very large numbers of files due to the additional system overhead required when Windows processes the files PKSFxX self extracting file sizes are limited to the size of an executable program file supported by the underlying operating system This currently is 2 GB for most operating systems This means you should not create a PKSFX file that is larger than 2 GB PKZIP will be able to create PKSFX files larger than this limit however they won t
