What should you use? 

Answer options:

A. AzCopy
B. Azure Storage Explorer
C. Azure portal
D. .NET Storage Client Library

A

You can copy blobs, directories, and containers between storage accounts by using the AzCopy v10 command-line utility. The copy operation is synchronous so when the command returns, that indicates that all files have been copied.
