An ARF file may refer to multiple formats, 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 timestamps that the Webex player uses for navigation, which is why typical players like VLC or Windows Media Player don’t support 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 commonly a Cisco Webex Advanced Recording Format capture created when a Webex meeting or training session is recorded, built to keep the interactive feel rather than output a simple video, which is why it may include audio, webcam video, screen-share streams, and metadata like navigation markers for accurate playback; because this structure is unique to Webex, typical players such as VLC or QuickTime fail to handle it, and the normal approach is to load it into the Webex Recording Player/Webex Player and convert/export it to MP4, unless a mismatched player version, corrupted download, or platform issues—Windows being more reliable—prevent it from opening.

To view an ARF file, remember it’s a Webex-only recording format, so you must let the Webex Recording Player/Webex Player interpret it, which tends to behave more reliably on Windows; after installing the player, try double-clicking the `.arf`, or open it manually via “Open with” or the File → Open menu, and if the recording refuses to load, the usual culprits are wrong player versions, in which case re-downloading or switching to Windows often works, after which you can convert it to MP4 inside the player.

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.

You can also rely on how big the ARF is: recording variants are usually massive, sometimes well over hundreds of megabytes, while report ARFs are far smaller thanks to text-based content; once you factor in the source—Webex for recordings, IT/security workflows for reports—you’ll almost always know which kind you’re dealing with and whether to use Webex Recording Player or the originating application.
