What is a DUC file

DUC files mostly belong to Action Replay by Datel. A DUC file is a Nintendo DS saved game state created by Action Replay video game cheat systems. Its contents are saved in a proprietary format used by Nintendo DS. Action Replay is a collection of portable devices used to apply cheat codes to game consoles such as the Xbox, PlayStation, and Nintendo series. Another type of DUC file is a data package used by SkyView stargazing mobile software.

How can I open a DUC file?

You need a suitable software like Action Replay to open a DUC file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your DUC file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a DUC file directly in the browser:.
