What is an ASTA file?

ASTA files mostly belong to Astah. ASTA files are container files that store StarUML diagrams. They use the ZIP format to compress and bundle the elements of a diagram.
Inside an ASTA file you will find the components of a diagram such as shapes, text, and connector information organized in a structured way.
These files are meant to be opened with the Astah software, which reads the zipped XML data and displays the diagram for editing and viewing.

Use Astah to open and work with the diagram.

You can also extract the file with any ZIP tool to view its underlying XML content.

The structure makes it easier to manage complex diagram data.

Astah
An .ASTA file is a ZIP-compressed archive containing a diagram created with Astah (formerly StarUML), a popular UML modeling tool. These files store various diagram types, including Class diagrams, Use Case diagrams, Sequence diagrams, and more. The internal structure of the archive includes XML files representing model elements, their relationships, and diagram layout information. Astah uses its own proprietary format within the archive, enabling features like code generation, reverse engineering, and model analysis. This file format is classified as Developer Files.
