What is a .autocad (dwg, dxf) file?
File extension details and usage information
DWG (Drawing) is a proprietary binary file format used for storing two- and three-dimensional design data and metadata. It is the native format for AutoCAD, a widely used computer-aided design (CAD) software developed by Autodesk. DWG files contain all the information a user enters when creating a drawing, including geometric data, maps, photos, and raster images, as well as the format of the drawing. It supports both 2D and 3D designs, making it suitable for a wide range of applications, including architecture, engineering, and manufacturing. The format is known for its ability to store complex designs with high precision. Due to its widespread use, DWG has become a de facto standard for CAD data exchange. While Autodesk provides viewers and converters, the format's proprietary nature has led to the development of alternative open formats like DXF for interoperability. DWG files are often large due to the amount of data they contain, and they can be version-specific, requiring compatible software versions for proper viewing and editing.

- Check whether the file is corrupted, incomplete, or encrypted.
A file extension alone does not guarantee whether a file is safe or unsafe. Only open files from trusted sources, scan unknown files before opening them, and be especially careful with executable, script, archive, and document files.
File safety tips
Use caution with unknown files
Only open files from trusted sources. Before opening a .autocad (dwg, dxf) file, scan it with antivirus software, verify that the file extension is expected, and avoid running unknown executable, installer, macro-enabled document, or script files.
