(AutoIt) Backblaze S3 List Bucket Objects

See more Backblaze S3 Examples

Demonstrates how to list the objects in a bucket.

The Chilkat S3 functions in the HTTP class are compatible with the Backblaze service. However, because of some specific issues, Chilkat v9.5.0.89 or later is needed.

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