With the extension mov, files are marked in Quicktime format.
These files usually contain video and audio streams. You can, however, in principle contain any file formats, as the Quicktime format is expandable.
Like AVI, Quicktime is a container format. Therefore, the extension makes no statement about the actual content of the file. It supports a large number of audio, image and video formats, all of which can be contained in various combinations in the file. In addition MOV files can also contain interactive content, panorama pictures, subtitles and chapters.
Some of this content can not be displayed if Quicktime is not installed. Most players only support normal videos in the MOV container.
The file contents can also be protected by DRM. Then you need the appropriate, possibly paid license to view the content. MOV files can also be streamed and are therefore often used on the internet.
Quicktime is developed by Apple as a proprietary solution and is therefore part of the operating system on the Apple Macintosh. The Quicktime software is also available for Windows for free.
For the Linux platform, there are several projects that develop a free open source software that will make Quicktime files usable under Linux.
However, many players can play MOV files as long as they can decode the format of the video and audio streams.
Quicktime is much more than a file format. It is intended as a complete platform for the production of videos and multimedia content. From the reception to the finished product. Therefore, the generation, editing and processing is usually reserved for paid programs and often found only in the professional market.
Most often resolving problems with opening MOV files is very simple. Just install an appropriate program that supports such files. All of the listed programs support MOV files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of MOV files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate MOV files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the QuickTime Player applications is not on the list, select "Browse" option in order to manually locate the directory where QuickTime Player has been installed.
Sometimes problems with opening MOV files may not lie with the application itself, but can arise due to other causes, such as:
