IronZIP allows the capability to modify an existing ZIP file. Begin by using the FromFile method to access the archive you wish to modify. After opening the archive, you can use the Add method to include files in the existing archive. Lastly, use the SaveAs method to export the modified ZIP file.

This feature enables you to easily update and expand your ZIP archives to accommodate your project's changing requirements. IronZIP simplifies archive management in your C# projects.
