ZipExtraField

public interface ZipExtraField

General format of extra field data.

Extra fields usually appear twice per file, once in the local file data and once in the central directory. Usually they are the same, but they don't have to be. {@link java.util.zip.ZipOutputStream java.util.zip.ZipOutputStream} will only use the local file data in both places.
