An ANIM file acts as a timeline-based motion file that holds instructions describing change over time rather than a static picture or final render, typically including duration, keyframes, and interpolation curves that shape how values evolve, affecting items such as object movement, rig or bone adjustments, sprite frame swaps, facial blendshape motion, or UI properties, and may also carry markers that activate events at set times.

The challenge is that ".anim" is simply a filename extension, letting different software implement their own animation data under that label, so an ANIM file’s structure varies by origin, with Unity providing a well-known example—its `.anim` files are AnimationClip assets within the `Assets/` folder, often accompanied by a `.meta` file and readable as YAML when "Force Text" serialization is enabled, and since ANIM files store motion data instead of rendered media, they usually must be opened by the source program or exported (FBX, capture, etc.) to be played.

".anim" has no single authoritative format because extensions are freeform labels that software authors can choose at will, allowing various programs to store completely different animation data under `.anim`—sometimes readable like XML, sometimes opaque and binary, sometimes proprietary—while operating systems still treat the extension as if it defines the file type, so many developers select `.anim` simply because it describes animation rather than adhering to a standard.

Since a single ecosystem can switch between text and binary output based on configuration, ANIM files become even more inconsistent, meaning the extension indicates "animation" rather than a unified format, and the correct approach is to identify the source tool or analyze details such as its folder context, associated metadata, or header markers to know how to open it.

An ANIM file is not a drop-in media format since it usually lacks rendered frames and only stores instructions about how objects or bones change over time, making it dependent on the software that created it, while real video files include pixel data for each frame plus audio/compression, allowing universal playback, meaning `.anim` files won’t open in VLC and must be exported through formats like FBX or recorded/rendered to become viewable outside their native environment.
