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

;  This example requires the Chilkat API to have been previously unlocked.
;  See Global Unlock Sample for sample code.

$oZip = ObjCreate("Chilkat.Zip")

;  The NewZip method only initializes the Zip object -- it does
;  not create or write a .zip file.

;  Add a references to all files in a directory tree.
;  Note: this does not read or compress the file contents --
;  it simply adds file references to the zip object.

;  Appends the contents of the zip object to the preExisting.zip
;  zip archive.  preExisting.zip is opened, and the files
;  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.
