How to open VMF file?

An often recurring problem with Valve Map Format is that VMF is not associated with the correct program file. Thus, when you open VMF, 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 VMF 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 Hammer Editor

The first step is to check if the computer has the Hammer Editor program installed. This can be achieved by typing Hammer Editor into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file VMF.

Programs to open VMF file

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

Step 2. Create association of Hammer Editor with VMF files

If, despite the installed application, the VMF file does not start in the Hammer Editor application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. 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. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the VMF file with the Hammer Editor application.

Step 3. Update Hammer Editor to the latest version

If, however, after binding Hammer Editor with Valve Map Format there were still problems, you should update the program to the latest version. In this case, use the Valve Corporation website or update the program from the application.

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

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This suggests truncating the VMF file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the VMF file that we want to open. Sometimes virus-infected VMF 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 VMF 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. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair VMF file corruption. You can restore the file from a backup or use Valve help.
The program can also signal the fact of encryption. The encrypted file VMF 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 of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. Copying the VMF 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. Closing other programs should help. Sometimes you have to wait for the session to the file VMF to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
