Iterate over Matching Filenames

See more Zip Examples

Iterates over files within a .zip that match a pattern. In this case, the pattern is "*.pem". This example will open a .zip containing files of type .txt, .cer, .pem, and possibly others, and will iterate over only the .pem files. Chilkat2 Java
