A WVX file is a WebEx Video File which is created by the WebEx video player software. This type of file is used by video conferencing software to stream video and audio over the internet. When a user wants to watch or participate in a WebEx video conference, they must download and install the WebEx software on their computer.

The WVX file contains information about the video conference, such as the URL where the video is being hosted, the name of the video, and other information about the video file. The WebEx software uses this information to display the video feed in the player and allow users to participate in the conference.

WVX files are not video files themselves but rather a reference to a streaming video file. This means that they do not contain any actual video data but instead provide a link to where the video can be found. Because these files are not actual video files, they are very small in size and can be easily shared through email or other means.

WebEx is one of the most popular video conferencing software used by businesses and organizations worldwide. Many companies use this software to conduct online meetings, training, and webinars. Because of its popularity, millions of WVX files are created every day.

In conclusion, a WVX file is a reference file that is used by the WebEx video player software to stream video over the internet. While these files do not contain any actual video data, they are essential for allowing users to participate in online video conferences. If you work in a company that uses WebEx, you likely encounter WVX files regularly when participating in video conferences or watching recorded sessions.
