The .gliffy file extension is associated with Gliffy diagrams. Gliffy is a web-based diagramming application that allows users to create various types of diagrams, including flowcharts, UML diagrams, network diagrams, and organizational charts. These diagrams are typically stored in a proprietary format that is specific to the Gliffy application. The .gliffy file contains the data representing the diagram, including the shapes, connectors, text, and other elements that make up the visual representation. To open and edit a .gliffy file, you generally need to use the Gliffy application itself, either through its web interface or a compatible plugin for platforms like Atlassian Confluence or Jira. While the format is primarily intended for use within the Gliffy ecosystem, there might be options to export diagrams to more common formats like SVG, PNG, or JPEG for sharing or integration with other tools. However, direct editing of the .gliffy file outside of Gliffy is typically not supported.
