An ARF file isn’t limited to one definition, but its most common use is the Cisco Webex Advanced Recording Format, which stores more than a basic “play-anywhere” video; unlike an MP4 that mainly holds encoded audio and video, a Webex ARF can bundle screen sharing, audio, optional webcam footage, and session details like chat data that the Webex player uses for navigation, which is why typical players like VLC or Windows Media Player fail to play it.

The common process is to use the Webex Recording Player/Webex Player to open `.arf` and convert it into MP4, and if opening fails, it often traces back to a player-version mismatch, since Windows tends to handle ARF files with fewer issues; in less frequent cases, `.arf` refers to Asset Reporting Format from security tools, which becomes clear if a text editor shows readable XML instead of binary output and large file size.
An ARF file is usually understood as a Cisco Webex Advanced Recording Format recording made when someone captures a Webex meeting or webinar, designed to preserve the full meeting experience rather than just a plain video, which is why it can store audio, webcam footage, screen sharing, and metadata like navigation points that help Webex play everything in sequence; these extras make the format Webex-specific, so common players like VLC or Windows Media Player can’t interpret it, and the standard fix is to open it in the Webex Recording Player/Webex Player and convert it—usually to MP4—unless the file is corrupted, the wrong player version is used, or ARF support behaves more reliably on Windows.
To get an ARF file open, rely on Webex’s own Recording Player because it’s the only tool that can interpret the metadata properly, particularly on Windows; once the player is installed, double-click the `.arf` or manually select it through Open with or File → Open, and if it fails to load, you’re likely facing OS-related limitations, in which case a new download or a Windows machine usually solves it, allowing you to convert it to MP4 afterward.
You can identify your ARF type by checking how it displays in a basic editor such as Notepad: if the content shows neatly readable structures—XML headers, tags, or recognizable labels—it’s probably a report or data-export file meant for security/compliance software, but if the file appears as unreadable binary clutter, it’s most likely a Webex recording stored in a proprietary container.
One more easy indicator is evaluating how large it is: Webex recording ARFs tend to be quite large due to video data, whereas report-oriented ARFs remain small and text-heavy, often just kilobytes to a few megabytes; when combined with the file’s source—Webex downloads for recordings versus compliance/auditing systems for reports—you can typically identify the format in under a minute and open it with either Webex Recording Player or the proper tool.
