An ANIM file is used as an animation-data container because it encodes motion through time rather than storing a finished clip, using keyframes and interpolation to define how properties shift, influencing objects, rigs, sprites, blendshapes, or UI visuals such as opacity and color, and sometimes embedding markers that fire triggers at chosen points.
The core problem is that ".anim" is not a universal format, so different programs store distinct animation data behind that extension, causing ANIM files to vary depending on origin, with Unity’s `.anim` AnimationClip assets inside `Assets/`—often bundled with `.meta` files and readable as YAML under "Force Text"—being among the best-known types, and since these files carry motion instructions instead of final imagery, they generally need the original software or an export method like FBX or captured rendering to be viewed or transformed.
".anim" is just an extension without guaranteed meaning, so multiple programs can use it for totally different animation data,
creating situations where one `.anim` file holds readable metadata in YAML, another is a binary chunk for a specific engine, and another is a proprietary format for a game tool, and because operating systems rely heavily on extensions for associations, developers often choose `.anim` for convenience rather than compliance with any shared format.
Even within one ecosystem, varied save options 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 isn’t a standalone video 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.
