A method, and associated system and computer program product, for retrieving a file from a distribution of storage nodes. A client computer sends a request for a file to a proxy layer and in response, the proxy layer generates a script for obtaining the requested file and sends the script to the client computer. The client computer executes the script, resulting in portions of the requested file being obtained from respective storage nodes in a storage layer. The portions of the requested file are concatenated to form the requested file.
