Notes about the WCU file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The WCU file type is primarily associated with 'CueCard' by Wade Brainerd. CueCard is a simple flash card program. It supports entering a list of questions and answers, and quizzing yourself on them.
