What is a URR file? A URR file is a signatures file created by Compuware Uniface, a development platform and fourth-generation programming language designed for building enterprise applications. It contains signatures, which define how application components, services, or external functions interact with one another. The signatures stored in URR files help ensure consistency in how applications handle data and execute tasks.

More Information URR files are used within the Uniface environment to manage and activate specific application features. They provide software developers, system integrators, and IT teams with a structured way to define the inputs, outputs, and behavior of components, making it easier to integrate new functionality into an application.
