Have you encountered a problem with a ASP file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a ASP file here. In the further part of this page we have added a list of programs that should open your ASP file. It is enough you choose a proper application for your operating system, download and install it.


The extension ASP stands for Active Server Pages.

This technology developed by Microsoft Corporation is used for the server-side creation of dynamic web pages. Files with the extension ASP are standard HTML documents in which one or more scripts are embedded. These scripts can be written in VBScript or JScript, the JavaScript alternative from Microsoft.

Because ASP files are typically run on a web server, any browser can be used to display the resulting document.

asp files are similar to PHP or CGI. The users never get to see the actual asp file, but only the created HTML page.

All you need to do to develop ASP pages is a text editor. Preferably, an editor that recognizes the language elements of ASP, color-coded and structured represents. There are also special applications that generate ASP code for specific applications, eg database connections.

Microsoft has discontinued the development of ASP. ASP.NET is the successor technology.

However, this uses the extension aspx.

The extension ASP is mostly used instead of htm or html on websites, if the server is running under Microsoft IIS or uses ASP.NET. There are also various extensions for other web server systems that allow you to execute ASP code.

Programs which can open a ASP file

How to open a ASP file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the ASP file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a ASP file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support ASP files. At this point we are looking for disk space where the application was installed in and we can link it with a ASP file. Since then, our operating system will use the selected program to support all ASP files.

Other issues

Despite the described problem with ASP there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the ASP file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the ASP file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
