An ARF file doesn’t represent just one format, though most often it refers to Cisco Webex’s Advanced Recording Format, which contains more than standard media; instead of behaving like an MP4 with simple audio–video tracks, a Webex ARF can include screen-share streams, audio, sometimes webcam video, and metadata such as timestamps that guide playback inside Webex, making regular players like VLC or Windows Media Player unable to open 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 wrong player release, 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 commonly denotes a Cisco Webex Advanced Recording Format meeting capture that aims to preserve the meeting environment instead of behaving like a normal video, packaging audio, webcam footage, screen-share content, and metadata like navigation tags which guide the Webex player; these extras make ARF incompatible with everyday players like VLC or Windows Media Player, which is why they don’t play it, and the go-to method is to open it in the Webex Recording Player/Webex Player and convert it to a standard MP4 unless issues such as corruption, using the wrong version, or weaker non-Windows support interfere.
Opening an ARF file means relying on the Webex Recording Player/Webex Player because only it can understand the ARF structure, especially on Windows where support is steadier; after installation, either double-click the `.

One simple method to determine the ARF type is to check its readability in a basic text editor—if Notepad 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.
A quick secondary test is to inspect the file size: recording ARFs from Webex are often huge, scaling from tens to hundreds of megabytes or more, while report-form ARFs remain relatively small because they’re mostly text; add in the origin—Webex links for recordings or IT/security tool exports for reports—and you can usually determine the correct type fast and choose either Webex Recording Player or the generating tool to open it.
