Opening an ASTA File
The ASTA file type is primarily associated with Astah.
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. FilExt.com note: For more details, visit the official Astah website.

How can I open an ASTA file?
You need a suitable software like Astah to open an ASTA file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ASTA file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ASTA file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert ASTA files:
- Astah
See the previous paragraphs to learn more about the main application. ASTA files are often referred to as Astah data files because this type of file is primarily created or used by this software.
- AstahAn .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.
ASTA file format:
The file format determines how the data is stored in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Below you will find our evaluation of the ASTA files:
The ASTA file extension is not widely used. Such a file is mainly used by one program with a specific format. But the following two file formats are common:
- 98% of all ASTA files use the ZIP format, that is, an ASTA file includes multiple compressed files. Such a ZIP file contains one file. Common included file names are EntityStore. Tip: If you rename the file ending to .zip and then double-click it, you see the included files and images. ASTA files are between 10 KB and 110 KB in size. The files contain the following words: EntityStore. Such ASTA files store data about diagram, case, class, diagrama, model, sequence, design, system and caso.
The remaining 2% of all ASTA files are different files with different signatures. These files are often connected to diagramas, activity, diagrams, analise or domain. Just click the "Choose your .asta file to analyze" button on this page to find out what your ASTA file is.
Technical Data for ASTA File Extension
an asta diagram file is a special file format and should only be edited and saved with the appropriate software.
How to solve problems with ASTA files
- Associate the ASTA file extension with the correct application.
- Update your software that should actually open diagram files. Because only the current version supports the latest ASTA file format. Search, therefore, e.g. on the manufacturer website after an available Astah update.
- To make sure that your ASTA file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
