An ARF file can be used for different kinds of data, but the most familiar meaning is Cisco Webex’s Advanced Recording Format, which goes beyond the straightforward audio/video content of an MP4; it can package screen sharing, audio, occasional webcam video, and session info like timestamps that the Webex player relies on, which explains why standard players like VLC or Windows Media Player don’t work with it.

The normal workflow is to open `.arf` in the Webex Recording Player/Webex Player and export it to MP4 for easy sharing, and if the file won’t load, it’s usually due to a system compatibility issue, with Windows offering better ARF support, and rarely `.arf` might be an Asset Reporting Format report, identifiable by checking the file in a text editor—XML means a report, whereas binary data and a large file size point to Webex content.
An ARF file is most often 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 session cues 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.
Opening an ARF file means relying on the Webex Recording Player/Webex Player because only it can interpret the recording, especially on Windows where support is steadier; after installation, either double-click the `.arf` or manually choose Open with → Webex player or File → Open, and if the player won’t load it, the recording may be corrupted, so re-download or switch to Windows if needed, then convert it to MP4 once playback works.
One simple method to determine the ARF type is to check its readability in a basic text editor—if TextEdit shows clean, structured information such as XML declarations or tag-based formatting, it’s likely a report/export file used by security or compliance systems, but if the editor presents messy, unreadable binary characters, that’s a strong sign it’s a Webex recording file that only Webex tools can interpret.
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.
