Classic ASP Google Cloud Storage: Copy File (Object) to another Bucket

Back to Index

Copies a fie (also known as an object) to another Google Cloud Storage bucket. This example copies the file "starfish.jpg" from the "chilkat-test" bucket to the "chilkat-images" bucket. In Google Cloud Storage, moving a file to a new bucket is a 2-step operation: First copy the file, then delete the original.
