# The below script is a sample piece of code wherein we are copying the blobs present in a folder inside a storage
# container of one storage account to another container in destination storage account along with folder.
# We are performing a listing of blobs and then copying them by matching the pattern
# The sample is doing a asynchronous copy of the blobs via COPY BLOB API in the backend
