An ANIM file usually represents animation data 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 difficulty is that ".anim" lacks a single governing standard, 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" is not one unified standard because a file extension is mostly just a label chosen by developers rather than a guaranteed spec like ".png" or ".pdf," allowing any program that handles animation to save its data using `.anim` even if the internal format differs completely, meaning one file might store readable text such as XML describing keyframes while another is a compact binary blob for a specific engine or a proprietary container for a certain game, and operating systems add to the confusion by relying on the extension for app association, so developers often pick `.anim` simply because it feels convenient or descriptive rather than standardized.

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 won’t open like a normal movie because it only contains motion instructions used by the software that produced it, while true video files include every pixel of every frame along with audio and timing, making them universally playable, so you can’t double-click an `.
