An ANIM file is mainly an animation sequence file rather than a static asset, often housing a timeline, keyframes, and rules that describe how values transition between frames, covering animated elements like positions, rotations, scales, bone rigs, 2D sprite frames, or blendshapes, plus UI changes such as opacity or color, with optional markers that launch events at certain times.

The issue is that ".anim" acts merely as a label rather than a universal standard, so different programs invent their own animation formats under that same extension, meaning one ANIM file can differ completely from another depending on its source, with Unity being one of the most common modern examples—its `.anim` files represent AnimationClip assets inside a project’s `Assets/` directory, often paired with a `.meta` file, and when "Force Text" serialization is enabled they may appear as readable YAML, while ANIM files in general hold motion data rather than rendered media and usually need the original software or an export workflow like FBX or video capture to be viewed or converted.

".anim" doesn’t guarantee a shared animation format since extensions aren’t regulated standards, so different programs can use `.anim` for unrelated animation systems, letting one file store structured text such as JSON, another hold binary engine data, and another serve as a proprietary package, while operating systems reinforce this ambiguity by choosing apps based solely on the extension, leading developers to use `.anim` mainly because it seems intuitive rather than because it follows a unified specification.

Within a single environment, save modes may cause an ANIM file to appear as readable text or compact binary, adding yet another layer of variation, so the term "ANIM file" conveys purpose rather than format, and the only reliable way to figure out how to open it is by tracing it back to the originating application or checking contextual indicators like folder placement, metadata files, or header information.

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 `.
