Compare CNC

You can compare CNC posts using File > Compare CNC.

Compare CNC enables you to compare the currently open post to another post on the disk. If the second CNC is from a newer version, an error is displayed. You must install DiffMerge (or another merge program capable of command prompt input) on your computer, and add the path of the executable to the XBUILDDIFF environment variable.
