How to open WMMP file?

The most common problem when using Windows Movie Maker Project Format is that a specific WMMP is not associated with the program. This is manifested by the fact that WMMP 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 WMMP 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 Windows Movie Maker

An often overlooked issue is to make sure that Windows Movie Maker is installed on the computer. The easiest method is to use the system search engine by entering the program name Windows Movie Maker in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support WMMP files.

Step 2. Create association of Windows Movie Maker with WMMP files

If, despite the installed application, the WMMP file does not start in the Windows Movie Maker 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 select the desired program. 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 WMMP file with the Windows Movie Maker application.

Step 3. Update Windows Movie Maker to the latest version

If, despite the association of the Windows Movie Maker program with the Windows Movie Maker Project 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 WMMP file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. Usually this applies to WMMP 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 operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the WMMP file that we want to open. As a result of the scan, sometimes it is not possible to recover WMMP files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of WMMP file may not always be supported by the latest software version. 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 the failure. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair WMMP 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 WMMP 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 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. It is best to move WMMP to a different directory.
This can happen on a file that does not support multiple access. In this case, the WMMP file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file WMMP to close. However, some background programs may block the WMMP file while scanning. If nothing helps, please reset the device.
