What is ASMX file?

The ASMX file has been categorized as Web Files. It was designed by Microsoft. Additionally, the Web Files category contains 303 of other files. ASP.NET Web Service Format is supported by 3 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Linux, Mac OS, Windows. There are also 13 alternative programs to handle the ASMX file. Adobe Dreamweaver, Adobe Contribute, ASP.NET, Microsoft Visual Studio will apply when it is not possible to use Visual Web Developer.

How to open ASMX file?

An often recurring problem with ASP.NET Web Service Format is that ASMX is not associated with the correct program file. This causes the file ASMX to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the ASMX 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 Visual Web Developer

In this case, you should first verify that the Visual Web Developer application is installed on the computer. To do this, enter the name Visual Web Developer into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open ASMX files.

Programs to open ASMX file

Remember to download programs supporting ASMX files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Visual Web Developer with ASMX files

If the application is or has been freshly installed, but the ASMX file still does not use the Visual Web Developer program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the ASMX file with the Visual Web Developer application.

Step 3. Update Visual Web Developer to the latest version

The fault may also lie with the Visual Web Developer program, it is possible that ASP.NET Web Service Format requires a newer version of the program.

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

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

Very often, the file may be size 0 or incomplete. Usually this applies to ASMX files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the ASMX file that we want to open. However, remember that not every infected ASMX file can be recovered, so it is important to take care of regular backups.
Older version of ASMX file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged ASMX files.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file ASMX except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. It is best to move ASMX to a different directory.
This problem usually affects more complex files. In this case, the ASMX file is blocked by the first application to open it. Closing other programs should help. Sometimes you have to wait for the session to the file ASMX to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
