* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loZip = CreateObject('Chilkat.Zip')

lnSuccess = loZip.OpenZip("qa_data/zips/sample.zip")

    ? loZip.LastErrorText
    RELEASE loZip

    * Note: In the ZIP file format, it is not required for a ZIP file to contain explicit directory entries. 
    * However, explicit directory entries can be included for convenience and compatibility with certain ZIP file processing tools and software.
    * An explicit directory entry in a ZIP file is an entry that specifically represents a directory, rather than a file. 
    * It usually has a directory name with a trailing slash (/) and zero-length content.
    IF (loEntry.IsDirectory) THEN
        ? STR(i) + ": " + loEntry.FileName + " (directory)"
    ELSE
        ? STR(i) + ": " + loEntry.FileName
    ENDIF

* Sample output:

* 0: aaa/ (directory)
* 1: aaa/pigs.json
* 2: bbb/ (directory)
* 3: bbb/base64Cert.txt
* 4: bbb/sub1/ (directory)
* 5: bbb/sub1/brasil_cert.pem
* 6: bbb/sub2/ (directory)
* 7: bbb/sub2/penguins.gif
* 8: bbb/sub2/starfish.jpg
* 9: hamlet.xml
* 10: hello.pdf
