ASPX is an extended version of Active Server Page. ASPX file format is developed by ASP.NET which is an open source Web application which is based on server side framework. The main purpose of this application is to develop dynamic websites, web based services and applications.
The programming language used in this framework is ASP and the files that save the source code are stored with .ASPX file extension. The working of ASPX file is similar to that of ASP but in ASPX a static HTML markup and other markups are added in the source file. Any browser can be used to open ASPX file.
When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the ASPX extension without any issue. However, if you still have problems with this, you may use the option of ASPX file conversion to a different format.
We hope we helped you solve the problem with the ASPX file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.
There can be more reasons which determine that you are not able to open the ASPX file (apart from the lack of the proper application installed).
First - the ASPX file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the ASPX file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the ASPX file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the ASPX file has not been completed and it cannot be opened properly).
