How to open DIAGSESSION file?

The main problem with Microsoft Visual Studio Diagnostic Session Format is that the DIAGSESSION file is incorrectly associated with programs. This causes the file DIAGSESSION to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the DIAGSESSION 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

An often overlooked issue is to make sure that Microsoft Visual Studio is installed on the computer. The easiest method is to use the system search engine by entering the program name Microsoft Visual Studio in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open DIAGSESSION files.

Programs to open DIAGSESSION file

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

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

However, it may happen that the application itself does not cause the DIAGSESSION file to open in the Microsoft Visual Studio application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the DIAGSESSION file with the Microsoft Visual Studio application.

Step 3. Update Microsoft Visual Studio to the latest version

If, despite the association of the Microsoft Visual Studio program with the Microsoft Visual Studio Diagnostic Session Format file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Microsoft Corporation page and install.

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

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The DIAGSESSION file may be unusually small compared to the original file. This suggests truncating the DIAGSESSION file contents when downloading or copying. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the DIAGSESSION file that we want to open. However, remember that not every infected DIAGSESSION file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the DIAGSESSION file. 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. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged DIAGSESSION files. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted DIAGSESSION files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
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. If possible, you can try to move the DIAGSESSION file to another location.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes you have to wait for the session to the file DIAGSESSION to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
