Example

[Visual Basic, C#, C++] The following example demonstrates how to compress/decompress file with EACompression Zip Component. Events are not shown here, please refer to Samples section to get the one of the file of EACompression.

Imports EACompression

        For i As Integer = 0 To count - 1
            Dim z As ZipFile = zs(i)
            oZip.ExtractTo(z, password, "c:\unzipped", overwrite)
        Next

        'another way is:
        'oZip.ExtractAll( "c:\uuzipped", password ) 

        'if you want to remove one of the file from this zip archive.
        'oZip.Remove( zs(0) )
    Catch ep As Exception
