Which command-line utility is optimized for transferring large files between a local computer and Azure File storage?

The command-line utility that is optimized for transferring large files between a local computer and Azure File storage is AzCopy. This tool is designed specifically for high-performance data transfer into and out of Azure storage services. AzCopy efficiently handles large datasets and accelerates the uploading and downloading of files, making it an ideal choice for operations involving substantial amounts of data.

Its capabilities include support for transferring files at scale, which is crucial for applications that require moving large volumes of data quickly and reliably. It also includes features such as resumable file transfers, which enhance its performance and reliability when dealing with extensive data transfers.

While Azure CLI and Azure PowerShell are valuable tools for managing Azure resources and performing various operations in Azure, they are not specifically designed for the high-performance transfer of large files. The AWS S3 CLI focuses on Amazon Web Services and is not relevant in the context of Azure File storage, thus making it an unsuitable option for this specific requirement.
