To edit an existing character, choose Open on the File menu, select the character's definition file (.ACD) in the resulting dialog box, and choose Open. The file will load into the Editor. Note that you cannot load compiled character files (.ACS, .ACF, or .AAF) with the Editor.
Because the character's definition file (.ACD) is a text file, you can also edit a character's definition by opening the file with a text editor or word processing program. However, when completing your changes, make sureto save the file in its original format before loading it into the character editor for compilation.
