What is an ARF file?

ARF files mostly belong to Webex by Cisco. ARF file extension is primarily associated with the Advanced Recording Format (ARF) for downloading video recordings of online meetings convened on Webex, a video-conferencing software developed by Cisco. The ARF format uses Network-based Recording (NBR) and a typical ARF file contains video, audio, list of attendees, chats, annotations, shared screens, and much more. Users may play, edit, or convert ARF files to common video formats such as WMV using Webex Player or Webex Converter. ARF file extension is also used to store some resources used by Active Tutor, an online education software which has been replaced by easy4C Tutor. Pacmania II, a legacy video game uses ARF as a game archive format for saving maps, 3D models, sounds, and other game resources.

ARF file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. File extension, signature and file format must match; otherwise errors will occur when the file is opened. When there is a problem with a file, the first step to solving it is to determine the file format. Below is our analysis of the ARF files:

65% of all ARF files start with the bytes 01 00 02 00, which are crucial for this file format.
