A ".BYU" file commonly denotes a BYU geometry file made of vertices and indexed faces, and checking it in Notepad is a quick way to tell: if the contents show clean numeric text—especially rows of three XYZ values—it’s probably the plain-text version; you’ll see an initial header of integer counts for components, vertex quantity, face quantity, and index totals, then a run of vertex coordinates and polygon faces written with 1-based indices, ending each face with a negative final index such as "10 11 12 -13," which signals the polygon boundary.

If opening the file in a text editor yields strange glyphs, it’s likely binary or not a BYU mesh, since ".byu" isn’t exclusive; a hex editor can reveal the truth—headers like "PK," "ftyp," or "RIFF" identify ZIP archives, MP4-family containers, or AVI/WAV files that simply carry the wrong extension, and renaming a duplicate to .zip, .mp4, or .avi for testing with 7-Zip or VLC is safe; if no recognizable header appears and the format doesn’t match the standard BYU structure, the only reliable opener is usually the original creator program, and a few lines of text or a hex screenshot helps me pinpoint it fast.

"Movie.BYU" is essentially the classic BYU mesh form built around two components: XYZ vertex coordinates and polygon faces defined by vertex indices with a negative final index indicating the face boundary, allowing the mesh’s structure to move between tools without additional metadata or overhead.

Movie.BYU is a *surface-geometry interchange* format precisely because it avoids embedding full scene data: no materials, no animation rigs, no cameras—just the surface, which makes it easy for analytical or visualization workflows to pass models between steps; the file layout typically opens with a brief header specifying counts, then moves into a simple XYZ vertex list whose floating-point coordinates represent the foundation of the surface to be connected later by polygons.

After the vertex list ends, the file encodes connectivity—indexed polygon definitions that join points into faces using 1-based integers and a negative final index to signal a completed polygon, a signature of BYU formatting; some files categorize polygons into parts for multi-component models, and because the format is geometry-centric, you won’t see textures, UVs, lights, or cameras—just the basic mesh made from vertex positions and polygon links.
