Why convert SHP to DEM?
An Esri Shapefile (introduced 1998) is a binary geospatial vector format storing geographic features and their attribute data. A .dem file is a binary game demo recording used by Quake, GoldSrc, and Valve Source engines (introduced 1996-2004) to replay recorded game sessions. The two formats describe entirely different domains - geographic data versus game engine replay data - and share no data structures, use cases, or conversion path.
About these formats
.SHP
Esri Shapefile (geospatial vector data)
A .shp file is almost always an Esri Shapefile - geospatial vector data (points, lines, polygons) used by GIS software. It is one piece of a set: it needs its sibling files (.shx, .dbf, and…

.DEM
Recorded Game Demo File
A DEM file is a recorded game replay that stores player inputs and network snapshots - not video frames. You watch it by placing it in the matching game's folder and using the in-game demo…

- No software can convert between these two unrelated formats as they serve entirely different purposes.
- If you need Shapefile data in another format, tools like QGIS or ogr2ogr can convert to GeoJSON, GML, or CSV.
- A
.demgame demo file can only be played back within its originating game engine (Quake, GoldSrc, or Source).
Frequently asked questions
What is a DEM file actually used for?
