'  Create a string array object with our set of filename patterns
'  to be excluded:

'  Tell the zip object to use these exclusions:
zip.SetExclusions sa

'  Append a directory tree.  The AppendFiles does
'  not read the file contents or append them to the zip
'  object in memory.  It simply appends references
'  to the files so that when WriteZip (or WriteZipAndClose,
'  or WriteExe, etc.) is called, the files are compressed
'  and encrypted.
recurse = 1
success = zip.AppendFiles("/temp/a/*",recurse)

success = zip.WriteZipAndClose()
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( zip.LastErrorText) & "</pre>"
    Response.End
End If

Response.Write "<pre>" & Server.HTMLEncode( "Zip Created!") & "</pre>"
