Opening an ASA File

The ASA file type is primarily associated with ASP.NET.

ASA	File extension: ASA
	File type:	startup/termination script

What is an ASA file?

ASA files mostly belong to ASP.NET by Microsoft. An ASA file is a script containing optional methods which run at the startup or termination of an ASP.NET (previously ASP) application lifecycle. This script is usually named Global.asa and saved in the root directory of a web application. ASP.NET is a .NET-based framework for building web applications and services. The ASA file may also contain methods which may be executed at the beginning or end of a network session. Newer versions of ASP.NET use ASAX filename extension instead of ASA. Another type of ASA file is an animation created by the ArcScene data visualization application in ArcGIS software suite.

How to open an ASA file

You need a suitable software like ASP.NET to open an ASA 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 ASA file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ASA file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert ASA files:

ASP.NET by Microsoft
See the previous paragraphs to learn more about the main application. ASA files are often referred to as ASP.NET web (source)s because this type of file is primarily created or used by this software.
Visual InterDev (startup/termination script) by Microosft
Visual InterDev is a discontinued component of an older version of Visual Studio integrated development environment. It used an ASA file to manage application and session startup/termination. This file format is classified as Web (source). Related links: Web Site File Types, Active Server Pages
Visual Studio (startup/termination script) by Microsoft
Visual Studio is an integrated development environment for building cross-platform applications. It can create and edit the Global.asa script containing ASP.NET application startup and termination methods. This file format is classified as Web (source). Related links: Web Site File Types, Active Server Pages
Visual Studio (startup/termination script) by Microsoft
Visual Studio is an integrated development environment with editing, source control, and compilation tools. It can create and edit the Global.asax script of an ASP.NET application. This file format is classified as Web (source). Related links: Web Site File Types, Global.asax Syntax

ASA file extension format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So you need a detailed analysis of a file to find out the format and the associated program. Below is our analysis of the ASA files:

ASA is seldom used as a file extension and covers different formats for different programs. The file formats most commonly found in ASA files are:

45% of all ASA files start with the magic bytes 00 00 00 00, which are always the first bytes of this file format. They consist of illegible, cryptic characters. ASA files are between 470 KB and 5 MB in size. This file type is based on cutting-edge technology. Several words can almost always be found in the files, e.g. pixel, 4. [Empty], 5. [Empty], 2. fox2, 410.0171, 6. [Empty], 106.8499, 3. [Empty] and 7. [Empty]. The file name 1.asa is typical for these files.
7% of all ASA files use the popular JetDB file format. The JetDB is a database format often used by Microsoft Access and Visual Basic programs. JET is short for Joint Engine Technology. These are binary files, so they do not contain words or text. ASA files are between 360 KB and 5 MB in size. The files contain the following words: Standard Jet DB. Files like these are about data.

All other ASA files (48%) have no consistent format, often e.g. ArcGIS ArcScene data, GZIP and HTML. The category is download, student, etma, collect or audit. Just click the "Choose your .asa file to analyze" button on this page to find out what your ASA file is.

How to solve problems with ASA files

Associate the ASA file extension with the correct application.
Update your software that should actually open startup/termination scripts. Because only the current version supports the latest ASA file format. Search, therefore, e.g. on the Microsoft manufacturer website after an available ASP.NET update.
To make sure that your ASA file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
