 # M-Stream Usage Notes
-Last updated on Aug. 15, 2019
+Last updated on April. 6, 2022
-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 network bandwidth, minimizes network latency, and increases resiliency, particularly for wide area networks.

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 required to be activated by license key for the enterprise on-premises File Fabric. It is not available for the Software-as-a-Service hosted solution.

-M-Stream will also accelerate the downloads to a Windows desktop running the SME Cloud tools version 10.5.10 or later, from one of the above providers.
+M-Stream will also accelerate moves, copies and renames (because renames require copying  the file that is being renamed) between buckets within an S3 or OpenS3 provider.
+M-Stream will also accelerate the downloads from one of the above storage providers to a Windows desktop running the SME Cloud Tools version 10.5.10 or later and to a Mac desktop with version 4.8 of the SME Mac Tools. M-Stream also provides accelerated uploads through the Web File Manager when storage for which M-Stream transfers are supported is used.
+## 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 'direct upload' enabled)
+  * Chunking is enabled (uncommon)
+  * File uploaded through FTP (as the file size is not provided)
+  * Encryption is enabled
+  * Antivirus scanning is enabled.
