How to open M3 file?

The most common problem when using Blizzard MDX3 Model Format is that a specific M3 is not associated with the program. Thus, when you open M3, 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 M3 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 StarCraft II

In this case, you should first verify that the StarCraft II application is installed on the computer. To do this, enter the name StarCraft II into the system search engine. 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 M3 files.

Remember to download programs supporting M3 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of StarCraft II with M3 files

If, despite the installed application, the M3 file does not start in the StarCraft II 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. 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 M3 file with the StarCraft II application.

Step 3. Update StarCraft II to the latest version

If, however, after binding StarCraft II with Blizzard MDX3 Model Format there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Blizzard Entertainment, Inc. page and install.

Step 4. Check for the following problems with the M3 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 M3 file may be unusually small compared to the original file. Usually this applies to M3 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 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. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the M3 file that we want to open. Sometimes virus-infected M3 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 M3 files changes over time. 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 this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair M3 file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Blizzard Entertainment
The program can also signal the fact of encryption. The encrypted M3 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. The problem is only writing to the file, not reading it. Copying the M3 file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. However, some background programs may block the M3 file while scanning. If the problem persists, restart the machine.
