What is a BROWSER file?

BROWSER files mostly belong to ASP.NET by Microsoft. A BROWSER file is a browser definition used by an ASP.NET web application. When a browser requests a resource from an ASP.NET server, the server uses information defined in a BROWSER file to determine the browser's capabilities and respond with the appropriate resource/format. To determine the browser's capabilities, ASP.NET first identifies the browser using information embedded in the request headers. The contents of a BROWSER file are written in Extensible Markup Language (without the header). Developers can create and edit a BROWSER definition using Visual Studio integrated development environment.

How to open a BROWSER file

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