Import Any Files is an extension that enables the simultaneous importing of multiple files into Blender. It removes the restriction of importing files one by one or by specific formats. The tool supports importing a mix of different file types in a single operation. Supported formats include FBX, OBJ, Alembic (ABC), STL, SVG, glTF, Collada (DAE), USD, USDA, USDC, and BVH.
