Dim zip As Chilkat.Zip

' When an absolute filepath is passed to AppendOneFileOrDir, the path within the .zip
' will be one of two values:  (1) just the filename part if saveExtraPath is False,
' or (2) the full absolute path, but made relative, if saveExtraPath is True.
' (For example, "c:/ck2000/appData/UnitTest/qa_data/hamlet.xml" made relative is 
' "ck2000/appData/UnitTest/qa_data/hamlet.xml")

saveExtraPath = False

If (success <> True) Then
    Debug.Print zip.LastErrorText
    Exit Sub
End If

' When a relative path is passed to AppendOneFileOrDir, then saveExtraPath does not apply.
' For example, assume our current working directory is "c:/ck2000/appData/UnitTest".  The following
' call to AppendOneFileOrDir creates an entry with the filepath "qa_data/hamlet.xml".
success = zip.AppendOneFileOrDir("qa_data/hamlet.xml",saveExtraPath)
If (success <> True) Then
    Debug.Print zip.LastErrorText
    Exit Sub
End If

' Examine the entries

numEntries = zip.NumEntries

i = 0

    Set e = zip.GetEntryByIndex(i)
    Debug.Print i; ": "; e.FileName

    i = i + 1
Loop

' The output so far is:

' 	0: hamlet.xml
' 	1: qa_data/hamlet.xml

' If we write the .zip as-is, then the zip will have two entries
' with the filepaths as shown above.

' This writes "qa_output/zipA.zip"
success = zip.WriteZip()

' Now change the entry filepaths to whatever is desired.

Set entry = zip.GetEntryByName("hamlet.xml")
