File TypeMaya Initial Fluid Cache File
What is an MCFI file?
Cache file created by Autodesk Maya, a 3D modeling program; stores fluid effects, such as liquids, smoke, fire, and clouds in a disk cache so they can be rendered more quickly.
MCFI files can be created by selecting Fluid nCache→Create New Cache within Maya. If multiple fluid objects are selected, fluid caches are created for each of the selected fluid objects.
Playback cache files are saved as .MCFP files.
