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 chat entries that the Webex player relies on, which explains why standard players like VLC or Windows Media Player won’t 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 corrupted download, since Windows tends to handle ARF files more reliably; 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 typically a Cisco Webex Advanced Recording Format file when a Webex meeting or webinar is recorded, and it’s designed to retain more than standard audio/video by including screen sharing and metadata like session points that help Webex replay the event in sequence; these specialized elements make ARF files incompatible with common players such as VLC or QuickTime, so they often fail to open, and the recommended fix is to use the Webex Recording Player/Webex Player to view and convert it—usually to MP4—unless the file is damaged, the wrong player version is used, or ARF support is more dependable on Windows.
To get an ARF file open, rely on Webex’s own Recording Player because it’s the only tool that can open the session content 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 a corrupt/incomplete file, in which case a new download or a Windows machine usually solves it, allowing you to convert it to MP4 afterward.
To quickly tell what kind of ARF you’re dealing with, open it using a plain editor like a simple text viewer: readable XML-like text, clear wording, or structured fields almost always means it’s a reporting/export format from compliance-related software, while binary gibberish or random symbols strongly suggests you’ve got a Webex recording container that normal text editors can’t make sense of.
A second simple clue is the overall file weight: Webex recording ARFs are usually quite big—often tens or hundreds of megabytes or even larger for long meetings—while report-style ARFs stay much smaller, typically in the kilobyte-to-megabyte range because they’re mostly text; combined with the source of the file—Webex links or meeting pages for recordings versus IT/security/compliance exports for reports—this check usually lets you confirm which type you have and decide whether to open it with Webex Recording Player or the tool that produced the report.
