What is .L4D file?
Settings file created by Cinema 4D, a 3D modeling application; saves a workspace layout and includes the positions of toolbars, palettes, and the editing canvas; can be used for setting up single or dual monitor configurations.
Users can create multiple L4D files that store layouts for different editing tasks. For example, while one perspective may be for editing 3D object geometry, another may have a better layout for animation.
