The code example demonstrates how to open an existing TAR archive and export it to a new TAR file using IronZip.

IronZip offers the capability to modify existing TAR files, making it a versatile tool for archive management in C# projects. To do so, start by utilizing the FromFile method, which grants access to the archive you wish to modify.

Once you've opened the archive, you can use the Add method to add files to the existing archive. This powerful feature simplifies the process of updating and expanding your zip archives, making it easy to adapt to your project's evolving needs.

Finally, use the SaveAs method to export the resulting TAR file.
