An ANIM file typically serves as an animation record because it stores motion over time instead of a single still image or a finished video, usually containing a timeline, keyframes, and interpolation rules that define how values shift between those keyframes, covering things like object transforms, bone motion, sprite changes, blendshape shifts, or UI tweaks such as opacity and color, sometimes with markers that trigger actions at specific moments.
The difficulty is that “.anim” is merely an extension, so unrelated software can assign their own animation formats to it, making ANIM files differ widely by source, with Unity’s usage being especially common—its `.anim` files act as AnimationClip assets kept in `Assets/`, generally paired with `.meta` files and occasionally readable in YAML via “Force Text,” and as motion-data containers rather than rendered media they typically require the generating program or an export path (FBX, recording, rendering) to play or convert.
“.anim” serves merely as an extension name, not a standardized format, meaning any animation-related tool can adopt `.anim` for its own internal structure, resulting in files that may be readable text like JSON, binary engine-specific data, or proprietary game containers, and because operating systems depend so heavily on the extension for opening rules, developers often pick `.anim` simply for clarity and convenience rather than compatibility.
Even within one ecosystem, alternate configuration choices can change how an ANIM file is stored—one tool might output a text-based version for version control while another uses a binary form for speed—adding even more variation, so “ANIM file” ends up describing its purpose rather than a strict format, meaning the only dependable way to know how to open it is to check the source application or look for clues such as folder context, nearby metadata, or the file’s header/signature.
An ANIM file doesn’t act as a typical media format because it stores animation logic—keyframes, curves, and which bones or properties move—rather than finished frames, so only the originating engine or tool can interpret it, while videos contain pixel data and timing that any media player can decode, leaving `.
