The ASPX file extension is for Active Server Page Extended Format. These web files work with Microsoft’s ASP.NET framework. Web browsers request ASPX webpages. Web servers then translate the ASPX files into HTML. Users see these HTML webpages in their browsers. ASPX pages can contain scripts in C# or VB.NET. The web server translates these into HTML too. ASPX files make dynamic web pages. These pages connect to databases. People use ASPX pages for: web apps, web services, websites.
ASPX files look like ASHX “web handler” files. But they are not the same. If an ASPX file download gets interrupted, it could be incomplete. Try downloading the file again if it does not open. Also, check you have permission to open the ASPX file.
To open an ASPX file, you need software like ASP.NET. On Windows, right-click the file. Choose “Open with” and pick a program. Sometimes an ASPX file wrongly renames a downloaded file. If a JPEG image downloads as an ASPX file, just rename it back to JPEG. Then open the file in an image viewer.
