The maximum file size is 2 GB because there's a limitation of the underlying API.</maml:para> <maml:para>The easy workaround would be to use the `ZipFile.CreateFromDirectory` Method (https://docs.microsoft.com/en-us/dotnet/api/system.io.compression.zipfile.createfromdirectory?view=net-6.0#system-io-compression-zipfile-createfromdirectory(system-string-system-string)). However, there are 3 limitations while using this static method:</maml:para> <maml:para> 1. The source must be a directory , a single file cannot be compressed. 2.
