What is ASPX file?

The .ASPX file is a server file. It is a dynamically generated website written in ASP.NET technology. This technology enables generating websites based on the user. The page code, which is sent to the end user, is not permanently stored on the server, but created on the request to open the page. This enables the use of advanced scripts and database connections. Pages written in this technology are usually more responsive.

How to open ASPX file?

The main problem with Active Server Page Extended Format is that the ASPX file is incorrectly associated with programs. Thus, when you open ASPX, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the ASPX file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Microsoft Visual Studio

The first step is to check if the computer has the Microsoft Visual Studio program installed. The easiest method is to use the system search engine by entering the program name Microsoft Visual Studio in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file ASPX.

Step 2. Create association of Microsoft Visual Studio with ASPX files

If the application is or has been freshly installed, but the ASPX file still does not use the Microsoft Visual Studio program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the ASPX file with the Microsoft Visual Studio program.

Step 3. Update Microsoft Visual Studio to the latest version

If, despite the association of the Microsoft Visual Studio program with the Active Server Page Extended Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Microsoft Corporation website or update the program from the application.

Step 4. Check for the following problems with the ASPX file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The ASPX file may be unusually small compared to the original file. This suggests truncating the ASPX file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file ASPX or the program directory. As a result of the scan, sometimes it is not possible to recover ASPX files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of ASPX file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged ASPX files. You can restore the file from a backup or use Microsoft help.
The program indicates that the file is encrypted or corrupted. The encrypted ASPX files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. Copying the ASPX file to another location will fix the problem.
This problem only occurs with more complex files. In this case, the ASPX file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the ASPX file again. Some anti-virus or backup software may occupy the ASPX file for a certain period of time. If the problem persists, restart the machine.
