Unzip all Files to a Single Directory (Ignoring Subdirectories in Zip)

See more Zip Examples

Demonstrates how to unzip all files into a single directory, ignoring the internal directory structure of the files in the .zip. VB.NET

Dim success As Boolean = False

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

Dim outDir As String = "c:/temp/testUnzipDir"

' Make sure our output directory exists.
Dim fac As New Chilkat.FileAccess
success = fac.DirEnsureExists(outDir)
If (success = False) Then
    Debug.WriteLine(fac.LastErrorText)
    Exit Sub
End If


Dim zip As New Chilkat.Zip

' In this example, the xml_files.zip contains some files in the subdirectories "dir1" and also "dir2/dir3".

' a1.xml
' b1.xml
' c1.xml
' dir1/a2.xml
' dir1/c2.xml
' dir2/dir3/c3.xml

success = zip.OpenZip("qa_data/zips/xml_files.zip")
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Unzip all files into the directory c:/temp/testUnzipDir
Dim numUnzipped As Integer = zip.UnzipInto(outDir)
If (numUnzipped < 0) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("Num unzipped = " & numUnzipped)

' After unzipping via UnzipInto, we have this:

' c:\temp\testUnzipDir\a1.xml
' c:\temp\testUnzipDir\b1.xml
' c:\temp\testUnzipDir\c1.xml
' c:\temp\testUnzipDir\a2.xml
' c:\temp\testUnzipDir\c2.xml
' c:\temp\testUnzipDir\c3.xml

zip.CloseZip()

Debug.WriteLine("Success.")
