M-Stream is a File Fabric feature that speeds up the uploading, downloading and copying of very big files. Large files are split into pieces, sent in parallel over multiple streams, and reassembled back into a contiguous file or object at the target. In this way M-Stream maximizes throughput over available network bandwidth, minimizes network latency, and increases resiliency, particularly for wide area networks. | M-Stream is a File Fabric feature that speeds up the uploading, downloading and copying of very big files.

+ | ## M-Stream for Upload | ||
+ | |||
+ | M-Stream streams parts in parallel directly to storage providers. M-Stream will not be used when an upload is performed outside the File Fabric, when the file size is not known, or when the file content will be encrypted. | ||
+ | |||
+ | For example when: | ||
+ | * Direct upload is used (when both client and provider have ' | ||

+ | * File uploaded through FTP (as the file size is not provided) | ||
+ | * Encryption is enabled | ||
+ | * Antivirus scanning is enabled. | ||
