What Are DEC Files?DEC files are Developer Files primarily associated with Magic: The Gathering Deck of Cards (Wizards of the Coast Inc. a subsidiary of Hasbro Inc.). (Other files may also be using the DEC file extension. If you know of any other software using the DEC file extension, please contact us so that we can update our information accordingly.)
Opening DEC FilesThe easiest way to open a DEC file is by double-clicking on it, which will let the computer decide the best way to open it according to the Windows DEC file association settings. If your computer opens your DEC file, but it's the incorrect application, you'll need to change your Windows registry file association settings. In other words, Windows is associating DEC file extensions with the wrong software program.
Is Your PC Healthy?I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster (Download) or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry. Happy Computing! :)
