An ARF file isn’t universally defined, 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 incompatible with it.
The usual method is to open the `.arf` file in the Webex Recording Player/Webex Player and use its convert/export feature to create an MP4 for easier viewing and sharing; if it won’t open, the cause is often a corrupted or incomplete download, since ARF handling is generally smoother on Windows, and in rarer cases `.arf` can mean Asset Reporting Format used by security tools, which you can identify by checking the file in a text editor—readable XML suggests a report, while binary gibberish and a large size point to a Webex recording.
An ARF file is generally 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 timing tags for accurate playback; because this structure is unique to Webex, typical players such as VLC or QuickTime can’t open 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.
Since ARF files are Webex-specific, you must use the Webex Recording Player/Webex Player to decode them correctly, and Windows generally offers the most reliable experience; after installing the player, open the `.arf` by double-clicking or via right-click → Open with or File → Open, and if it refuses to load, the usual reasons are incomplete downloads, so re-download or try a Windows system, then export to MP4 for universal playback.
A quick way to figure out which ARF type you have is to see whether it acts like a text-based report or a binary recording container: if you open it in a simple editor like Notepad and you see readable structured text such as , along with clearly legible fields, it’s probably a report/export file used by security or compliance tools, but if you instead get mostly unreadable symbols and binary-looking noise, it’s almost certainly a Webex recording stored in a format that normal editors can’t interpret.

An additional quick hint is to see how big it appears: 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.
