An ARF file can denote different formats, but the best-known example is Cisco Webex’s Advanced Recording Format, which includes more than ordinary video/audio; it bundles screen-sharing streams, audio, sometimes webcam footage, and session elements like markers that help Webex navigate the recording, which is why common media players like VLC or Windows Media Player can’t play it.
The standard approach is to load the `.arf` file through the Webex Recording Player/Webex Player and then convert it to MP4 for simpler playback, with opening failures frequently caused by a platform limitation, especially since ARF support is more dependable on Windows, and occasionally `.arf` may instead be an Asset Reporting Format file from security software, which you can spot by opening it in a text editor—XML text means a report, while binary noise and bigger size indicate Webex media.

meeting or webinar, meant to retain the meeting’s flow rather than act like a basic video, so it bundles audio, camera video, screen-sharing content, and metadata like timeline markers that Webex uses to navigate playback; such features make it incompatible with regular media players, which explains why VLC or Windows Media Player can’t play it, and the standard method is to open it in the Webex Recording Player/Webex Player and convert it to MP4 unless the file is incomplete, corrupted, or impacted by platform differences in ARF support.
Opening an ARF file means relying on the Webex Recording Player/Webex Player because only it can parse the session data, 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 partially downloaded, so re-download or switch to Windows if needed, then convert it to MP4 once playback works.
An easy test for determining your ARF variant is to open it in a lightweight text editor like Notepad: if you immediately see structured, readable text including XML-like tags or descriptive fields, it’s likely a report/export file used by compliance tools, whereas a screen full of binary-like chaos and random symbols is a strong indicator that it’s a Webex recording that standard text editors can’t interpret.

An additional quick hint is to review file size: Webex recording ARFs often balloon into tens or hundreds of megabytes, even gigabytes, while report-style ARFs stay much smaller because they’re text-driven; match this with the origin—recordings coming from Webex pages and report files coming from compliance or auditing exports—and you can usually identify the correct type rapidly and open it with the proper program.
