An ANIM file acts as a timeline-based motion 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 complication is that “.anim” serves only as an extension and various tools use it for unrelated animation systems, so two ANIM files may share nothing except the name, with Unity being a major modern user—its `.anim` files are AnimationClip assets stored in `Assets/`, typically alongside a `.meta` file, and under “Force Text” serialization they show up as readable YAML, and because ANIM files hold motion instructions rather than final imagery, they normally require the creating application or an export step such as FBX output or recording to be viewed or processed.

“.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 XML, 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 user settings, 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 isn’t built for general playback 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 `.anim` files unplayable by VLC and requiring export steps such as FBX or rendering to create a watchable version.
