Have you encountered a problem with a FLV file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a FLV file here. In the further part of this page we have added a list of programs that should open your FLV file. It is enough you choose a proper application for your operating system, download and install it.


The FLV extension identifies Flash video files. By using it on Youtube and similar sites, it has become the standard format for streaming Internet video.

The format was developed by Macromedia and is being further developed by Adobe today. It's a proprietary format, but it's also made available to other developers.

Like MOV, FLV is a container format. The files contain a video and audio stream as well as metadata. The included audio and video data may be encoded using various compression techniques. Which ones are depends on the desired compatibility with the Flashplayer plugin. With higher versions, other methods are available that also support HD resolutions.

Any browser with Adobe Flashplayer plugin can play FLV files.

How to open a FLV file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the FLV file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a FLV file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support FLV files. At this point we are looking for disk space where the application was installed in and we can link it with a FLV file. Since then, our operating system will use the selected program to support all FLV files.

Other issues

Despite the described problem with FLV there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the FLV file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the FLV file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
