CopyPart Method
Copies the specified object as a part of a multipart upload.
procedure CopyPart(SrcObjectName: String; DestBucket: String; DestObjectName: String; DestPartNumber: Integer; DestUploadId: String);
Remarks
This method copies data from the object specified by SrcObjectName (in the bucket currently selected by Bucket) to a new multipart upload part for DestObjectName in DestBucket.
The DestPartNumber and DestUploadId parameters should be used in the same manner as the UploadPart method's PartNumber and UploadId parameters.
To copy a specific range of bytes from the source object, set the CopyPartRange configuration setting before calling this method.
