First, "Dehancer" is likely the name of the software. I remember Dehancer is a video grading plug-in for Adobe After Effects and other hosts. The ".Pro.OFX" part probably refers to the version and format. OFX is the OpenFX format used for visual effects plugins, so this might be the OpenFX version of Dehancer Pro. The version number is 7.1.3, which I can check if there are any newer versions or known issues. The "CE" could stand for Creative Edition or Community Edition, but I'm not entirely sure. The ".rar" extension indicates it's a compressed archive, likely containing the software or its components.
