AVB may indicate different things in different environments, and the .AVB extension most commonly corresponds to an Avid Bin used in Avid Media Composer to store project metadata including clips, subclips, sequences, and markers, with the actual media housed outside the bin in locations like `Avid MediaFiles\MXF`; bins must be opened within Avid, and if media appears offline it usually signals missing files, while non-Avid uses of "AVB" in networking or Android security don’t refer to openable files at all.

In pro A/V and certain automotive Ethernet environments, AVB represents Audio Video Bridging, an IEEE framework ensuring synchronized, bandwidth-reserved media over Ethernet rather than defining a file format; in Android firmware work, AVB instead means Android Verified Boot, which validates partitions during startup using elements like `vbmeta`, and older software may also assign `.avb` to Microsoft Comic Chat Character files when not tied to Avid.

How to open an AVB file varies with the type of AVB involved, but in the usual Avid Bin (.avb) scenario, you open it only through Avid Media Composer by loading the project and then opening the bin, which shows your clips and sequences; Media Offline errors typically point to missing or displaced `Avid MediaFiles\MXF` rather than a bad bin, so reconnecting or relinking fixes it, and if the bin is unreadable, Avid Attic provides automatic backups you can restore.

If your "AVB" points to Audio Video Bridging, there isn’t a standalone file at all, because AVB is a networking standard for timed media over Ethernet, so you configure compatible switches and interfaces rather than open a file; if it refers to Android Verified Boot, you’re dealing with firmware elements such as `vbmeta` that require platform tools to inspect, and if it’s the uncommon Microsoft Comic Chat Character `.avb`, only vintage Microsoft programs or emulators typically read it.

An Avid Bin (`.avb`) doesn’t include the underlying media, holding information about clips, sequences, timecode usage, and markers, while your actual audio/video files live elsewhere under directories such as `Avid MediaFiles\MXF\...`; copying just the `.avb` moves the edit instructions but not the footage, so Avid will load the bin but show Media Offline until the media is accessible or relinked, and this design keeps bins compact for sharing and backup—so an `.
