An ANIM file commonly functions as an animation descriptor that tracks changes across a timeline instead of outputting a completed video, with keyframes defining key moments and interpolation guiding what happens in between, applying movement to things like transforms, rigging, sprite cycling, blendshapes, and UI attributes such as color or opacity, and may also include markers that invoke actions during playback.
The catch is that “.anim” isn’t a standardized animation format, allowing different programs to create incompatible animation files under the same name, with Unity being a primary modern case where `.

“.anim” isn’t restricted to one animation definition 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 `.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 serialization options, 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 doesn’t contain playable imagery 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.
