How to open W3M file?

An often recurring problem with Warcraft 3 Map Format is that W3M is not associated with the correct program file. This is manifested by the fact that W3M files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the W3M 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 Warcraft III: Reign of Chaos

The first step is to check if the computer has the Warcraft III: Reign of Chaos program installed. The easiest method is to use the system search engine by entering the program name Warcraft III: Reign of Chaos 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 W3M files.

Step 2. Create association of Warcraft III: Reign of Chaos with W3M files

If, despite the installed application, the W3M file does not start in the Warcraft III: Reign of Chaos application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. 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. The "always use the selected program ..." field will set the Warcraft III: Reign of Chaos application as the default for handling the W3M file.

Step 3. Update Warcraft III: Reign of Chaos to the latest version

If, however, after binding Warcraft III: Reign of Chaos with Warcraft 3 Map Format there were still problems, you should update the program to the latest version. In this case, use the Blizzard Entertainment, Inc. website or update the program from the application.

Step 4. Check for the following problems with the W3M file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The W3M file may be unusually small compared to the original file. This suggests truncating the W3M file contents when downloading or copying. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our W3M file. Sometimes virus-infected W3M files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the W3M files changes over time. 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. Sometimes the program itself has options to repair the most popular W3M file corruption. The easiest way to restore the file is from a backup or by contacting Blizzard Entertainment, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted W3M files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
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 W3M file to another location will fix the problem.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file W3M to close. However, some background programs may block the W3M file while scanning. If the problem persists, restart the machine.
