ASP File - opening and understanding

Did your computer fail to open an ASP file? We explain what they are used for and recommend software that we know can open or otherwise handle your .ASP files.

What is an ASP file?

ASP stands for Active Server Page. Files that contain the .asp extension contain scripts which are used to generate HTML pages. In other words, when your web browser requests an .asp page, the web server will generate the content to display in the browser on-the-fly. The page is not just downloaded from the server, but built by the server for that specific user. ASP files are commonly used by sites that are hosted on Microsoft IIS servers.

When visiting a web page with a URL that ends in .asp, you know that you are on a website that is generated by a Microsoft server using ActiveX scripting. The ASP files that are used to create the page allow websites to remain dynamic without the need for re-coding or constant site updates.
