Append Dir Tree to Existing Zip w/out Rewriting Entire Zip

See more Zip Examples

Demonstrates how to use the QuickAppend method to append a directory tree 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. AutoIt

; See Global Unlock Sample for sample code.

; referenced by this zip object are streamed in, compressed,
; and appended to the end of the archive.

; Note: Additional files, directory trees, or in-memory data
; can be appended by calling AddFile, AppendFiles,
; AddString, AddBd, AddSb, 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
