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.

Dim zip As New ChilkatZip

If (success = 0) Then
    Debug.Print zip.LastErrorText

End If

' Add a file and preserve its relative directory structure
' within the ZIP archive.

' The following file:
'     c:/projects/app/docs/readme.txt

' Will be stored in the ZIP as:

success = zip.AddFile("c:/projects/app/docs/readme.txt",saveExtraPath)

    Exit Sub

' Add a file using only the filename in the ZIP archive.
