(AutoIt) Append Files to Existing Zip w/out Rewriting Entire Zip

Demonstrates how to use the QuickAppend method to append files to an existing .zip archive. This method works by editing the existing .zip -- it does not rewrite or recompress the contents of the existing .zip. It is the fastest way to append additional files to a pre-existing large .zip archive. Note: The QuickAppend method is new and available in the pre-release downloads, or in official releases dated after 6-October-2007.

; Note: Additional files, directory trees, or in-memory data
; can be appended by calling AppendOneFileOrDir, AppendFiles,
; AppendString, AppendData, etc. multiple times.
; Whatever files and/or in-memory data that are referenced by
; this zip object will be appended to preExisting.zip when
; QuickAppend is called
