The invention describes a system for distributing a software file from a source to a plurality of targets in such a manner that only portion of the file is received and stored in a file distributor. The file distributor has a flow mediator, which provides data flow control in such a manner that the stored portion of the file is forwarded to the targets asynchronously in order to provide that each target receives the portion of the file at its own rate. A corresponding method for the distribution of software is also provided.
