editor

Machine-translated from the German article

An editor (from English to edit [texts etc.] 'to publish', 'to edit', 'to revise', but also [films] 'to cut'), also called an editing program in German, is a computer program for creating and editing digital data (files). By contrast, a file viewer is only used for viewing data and generally works with read access only. Working with an editor differs significantly from the traditional paper-based way of working, since the edited data is kept in volatile memory until the editor explicitly decides to save previously entered or edited data.
