Example

The For Each Blob in Container activity can be used to process multiple blobs stored in an Azure Blob Storage container. In this example, the activity retrieves each blob from the container and uses the CurrentItem variable to identify the blob being processed.

Workflow

1. Add an Azure Scope activity to the workflow and provide the required Azure Storage credentials.
2. Add the For Each Blob in Container activity inside the Azure Scope.
3. Specify the Azure Blob Storage container in the Container field.
4. Keep the default CurrentItem variable in the For Each field.
5. Add the Download File activity inside the For Each Blob in Container activity to download each blob.
6. Use CurrentItem in the Download File activity to refer to the blob currently being processed.
7. Specify the local path where the blob needs to be downloaded.
8. Run the workflow.

The activity retrieves each blob from the specified container and uses the Download File activity to download the blobs sequentially to the configured local location.
