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.

    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    CkZip zip = new CkZip();

    success = zip.NewZip("addFileExample.zip");
    if (success == false) {
        System.out.println(zip.lastErrorText());
        return;
        }

    //  Add a file and preserve its relative directory structure
    //  within the ZIP archive.
    //  
    //  The following file:
    //      c:/projects/app/docs/readme.txt
