What is MTS file?

The .MTS file is a video file. The AVCHD format is used here, which was developed by SONY and Panasonic in 2006 to save high-quality video on Blue-Ray discs. Devices of these companies have implemented support for this format, as well as their proprietary software. Other software (especially high-end software) can also edit these files. .MTS files mainly concern material obtained from the video recorder. Files ripped from Blue-Ray discs usually have the .M2TS extension.

How to open MTS file?

An often recurring problem with AVCHD Video Format is that MTS is not associated with the correct program file. This causes the file MTS to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the MTS 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 Toast 11

An often overlooked issue is to make sure that Toast 11 is installed on the computer. To do this, enter the name Toast 11 into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support MTS files.

Programs to open MTS file

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

Step 2. Create association of Toast 11 with MTS files

If, despite the installed application, the MTS file does not start in the Toast 11 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. 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 Toast 11 application as the default for handling the MTS file.

Step 3. Update Toast 11 to the latest version

If, however, after binding Toast 11 with AVCHD Video Format there were still problems, you should update the program to the latest version.

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

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The MTS file may be unusually small compared to the original file. This suggests truncating the MTS file contents when downloading or copying. The only repair option is to download the file again.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the MTS file that we want to open. As a result of the scan, sometimes it is not possible to recover MTS files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the MTS files changes over time. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged MTS files.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file MTS 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. While there is usually no problem reading such a file, it may not be possible to save it. Copying the MTS 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 MTS to close. Some anti-virus or backup software may occupy the MTS file for a certain period of time. If the problem persists, restart the machine.
