How to unzip files in blackberry

I'm developing an app开发者_运维技巧 that manages a file zip with directories and files. I must know how to unzip these files in order to create in local the same structure as in the zip file.

Thanks in advance :)

There are no native APIs on BlackBerry that support ZIP archives. You may have to Google around for third party packages or libraries to do this for you.
