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 cue actions 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" doesn’t represent one fixed structure 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 JSON 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.

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 cannot be treated like MP4/MOV/AVI/GIF because it holds animation data—keyframes, curves, property changes—instead of finished frames, requiring interpretation by the creating engine or tool, whereas video files store frame-by-frame pixels any player can show, so an `.anim` typically won’t open in VLC and must be converted through exports like FBX or through rendering/recording to become watchable.
