Different types of files are used to store data. ASPX is one of them. The term ASPX is an abbreviation for Active Server Pages.

They contain scripts and source codes that help a browser the communicate loading of web pages.

When a URL has an extension ASPX at the end, it means that the web page is running on the ASP.NET framework. It falls into a similar category of files with .html and .php. The data of all of these file types are processed by a web server to display the results. Windows don’t support ASPX files by default, and this is why you will need special workarounds to open them.

What are ASPX Files used for?

ASPX files are used for Microsoft’s ASP.NET framework for the operation of web pages. Websites consist of a complicated set of configurations at the back end. One type of configuration is achieved using ASPX files, also known as Active Server Pages. Web servers use them to run ASP.NET server-side web application framework.

ASPX files are only used for back end configurations. So, the users don’t see or interact with such types of files commonly. If they are seeing it, this might mean that something is wrong with the server of the web page that the admin should fix.
