Embodiments relate to message switch file sharing. A file is accessed by a computer processor of a client producer device to share with a plurality of client consumer devices across a network. The computer processor partitions the file into a sequence of message payloads associated with a topic and a scheme. The scheme defines a sequence identifier to establish an order to reassemble the sequence of message payloads into the file. A sequence of messages is formed including the topic and the sequence of message payloads. The sequence of messages is published to a message queue associated with the topic in a message switch in the network. The message switch provides the client consumer devices with access to the sequence of message payloads based on subscriptions to the topic.
