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 can’t load 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 wrong player version, since ARF handling is typically better 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 typically the result of recording a Webex meeting in Cisco’s Advanced Recording Format, which aims to preserve the complete session rather than output a simple media file, meaning it can hold audio, webcam video, the screen-share feed, and metadata like timing points that Webex needs for structured playback; because this structure is Webex-specific, players like VLC, Windows Media Player, or QuickTime fail to open it, and the usual solution is to use the Webex Recording Player/Webex Player to convert it to MP4, unless a wrong player version, corrupted ARF, or platform differences (Windows being more reliable) get in the way.
Since ARF files are Webex-specific, you must use the Webex Recording Player/Webex Player to open 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 player mismatches, so re-download or try a Windows system, then export to MP4 for universal playback.
A fast way to identify your ARF file is to check whether it resembles plain text or binary data: opening it in something like TextEdit and seeing obvious readable XML-like lines, tags, or structured words usually means it’s a report/export file used by certain compliance tools, whereas seeing garbled characters or dense binary junk nearly always indicates a Webex recording that regular editors can’t display properly.

One more easy indicator is evaluating how large it is: Webex recording ARFs tend to be quite large due to video data, whereas report-oriented ARFs remain small and text-heavy, often just kilobytes to a few megabytes; when combined with the file’s source—Webex downloads for recordings versus compliance/auditing systems for reports—you can typically identify the format in under a minute and open it with either Webex Recording Player or the proper tool.
