Add Files to a ZIP Using AddFile

See more Zip Examples

This example demonstrates how to use the AddFile method to add files from the local filesystem to a ZIP archive.

The example adds two files:

• One file with its relative directory path preserved
• One file stored using only its filename

The AddFile method adds references to local filesystem files. The files are not actually read or compressed until a Write* method is called.
