An ANIM file is commonly an animation-format 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 trigger functions at set times.

The challenge is that “.anim” isn’t tied to one definition, 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 JSON, sometimes opaque and binary, sometimes proprietary—while operating systems still treat the extension as if it defines the file type, so many developers select `.

Even inside the same toolset, export modes can switch an ANIM file between text and binary, increasing inconsistency, which is why “ANIM file” refers more to its animation function than to a fixed structure, making it necessary to identify the originating software or examine hints like its directory location, companion metadata, or header signature to determine how it should be opened.

An ANIM file isn’t a ready-to-play format since it carries instructions—such as keyframes and curves—not actual frames, meaning only the originating engine can interpret it, in contrast to video formats containing pixel data for all frames, so media players can show them instantly, which is why `.anim` files don’t play in VLC and must be exported (FBX) or rendered to produce a standard video format for general viewing.
