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. Subscription information is stored on the message switch in one or more access control lists associated with the message queue.
