What is M15 file?

The M15 file has been categorized as Video Files. The author of this format is Moving Picture Experts Group. Additionally, the Video Files category contains 546 of other files. MPEG Video appears on 2 operating systems as a functional file. These systems consist of Mac OS, Windows, although it may occasionally be found on another system, it will be non-functional. The main program that supports this format is QuickTime Player. This was created by Apple, Inc.. This file type can also be opened by 4 other programs. You can use iTunes, Windows Media Player in case QuickTime Player cannot be used.

How to open M15 file?

The main problem with MPEG Video is that the M15 file is incorrectly associated with programs. This causes the file M15 to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the M15 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 QuickTime Player

An often overlooked issue is to make sure that QuickTime Player is installed on the computer. This can be achieved by typing QuickTime Player into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open M15 files.

Step 2. Create association of QuickTime Player with M15 files

If the application is or has been freshly installed, but the M15 file still does not use the QuickTime Player program, it means no 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. 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. Checking the "Always use the selected program ..." box will permanently associate the M15 file with the QuickTime Player program.

Step 3. Update QuickTime Player to the latest version

If, despite the association of the QuickTime Player program with the MPEG Video 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 Apple, Inc. page and install.

Step 4. Check for the following problems with the M15 file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The M15 file may be unusually small compared to the original file. This suggests truncating the M15 file contents when downloading or copying. The only repair option is to download the file again.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the M15 file that we want to open. However, remember that not every infected M15 file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the M15 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 the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular M15 file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Moving Picture Experts Group
The program can also signal the fact of encryption. The encrypted file M15 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 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. If possible, you can try to move the M15 file to another location.
This problem usually affects more complex files. In this case, the M15 file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the M15 file for a certain period of time. If this does not work either, restart the device.
