There is only one file type that uses the .WOP extension:
Wonderland Object Preset
Object preset file for Wonderland Adventures Editor, a program used to create and edit levels for Wonderland Adventures; a hex file that contains 3D models, character movements, logic data, level parameters, and other data.
WOP files can be edited to make additional object presets. They are used to create objects for custom adventures in the editor.
