What is MASTER file?

The file with the extension MASTER is the Web Files file type. The creator of this file is Microsoft. Additionally, the Web Files category contains 303 of other files. ASP.NET Master Page appears on 1 operating systems as a functional file. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional. The main program that supports this format is Microsoft Visual Studio. This was created by Microsoft Corporation. There are also 3 alternative programs to handle the MASTER file. The Adobe Dreamweaver, Visual Web Developer, ASP.NET programs will also handle the file when the Microsoft Visual Studio program does not fulfill its role.

How to open MASTER file?

The main problem with ASP.NET Master Page is that the MASTER file is incorrectly associated with programs. This is manifested by the fact that MASTER files open in unusual applications or do not have an assigned program. How to solve such a problem?

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

In this case, you should first verify that the Microsoft Visual Studio application is installed on the computer. This can be achieved by typing Microsoft Visual Studio into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file MASTER with Microsoft Visual Studio. Later in this article you will find a list of programs that can open MASTER files.

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

If the application is or has been freshly installed, but the MASTER file still does not use the Microsoft Visual Studio program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. 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. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Microsoft Visual Studio application as the default for handling the MASTER file.

Step 3. Update Microsoft Visual Studio to the latest version

The fault may also lie with the Microsoft Visual Studio program, it is possible that ASP.NET Master Page requires a newer version of the program. 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 MASTER 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. This is most often caused by a problem while downloading the MASTER file. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our MASTER file. As a result of the scan, sometimes it is not possible to recover MASTER files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of MASTER 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.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair MASTER file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft
When reading, a message appears that the file was encrypted or corrupted. The encrypted MASTER 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.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. Copying the MASTER file to another location will fix the problem.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file MASTER to close. However, some background programs may block the MASTER file while scanning. If this does not work either, restart the device.
