Palette data file used by AutoCAD, a 3D design and documentation CAD application; stores the definitions of tools in a palette located within the AutoCAD user interface; used for exporting individual palettes that can be imported by another AutoCAD installation. Tool palettes are stored locally in .ATC files. However, ATC files cannot be shared directly with other users. Therefore, you should use XTP files for sharing palettes.
Data format saved by XTree, a popular DOS/Windows disk management utility in the 1980s and early 1990s.
File extension is used by XTrkCAD. Parameters or demo file.
