The TRD file format, specifically associated with Ray Dream Studio, was originally developed by Ray Dream Inc. for the purpose of storing complex three-dimensional scene data. These files typically encapsulate geometry, texture mappings, lighting configurations, and animation parameters used within legacy 3D modeling and rendering software applications. Now considered an obsolete format, TRD files are primarily encountered in historical digital archiving and pose negligible security risks because they do not support executable content.
