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.
