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.

VB.NET

Dim success As Boolean = False

Dim zip As New Chilkat.Zip

success = zip.NewZip("addFileExample.zip")
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
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:
'     projects/app/docs/readme.txt
' 
Dim saveExtraPath As Boolean = True
success = zip.AddFile("c:/projects/app/docs/readme.txt",saveExtraPath)
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Add a file using only the filename in the ZIP archive.
' 
' The following file:
'     c:/temp/logo.png
' 
' Will be stored in the ZIP as:
'     logo.png
' 
saveExtraPath = False
success = zip.AddFile("c:/temp/logo.png",saveExtraPath)
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Write the ZIP archive to disk and close it.
' The source files are consumed at this time.
success = zip.WriteZipAndClose()
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("ZIP archive created successfully.")
