What Are CNA Files?CNA files are Data Files primarily associated with Catena Data File (OpEx Software LLC). (Other files may also be using the CNA file extension. If you know of any other software using the CNA file extension, please contact us so that we can update our information accordingly.)
Opening CNA FilesThe easiest way to open a CNA file is by double-clicking on it, which will let the computer decide the best way to open it according to the Windows CNA file association settings. If your computer opens your CNA file, but it's the incorrect application, you'll need to change your Windows registry file association settings. In other words, Windows is associating CNA 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! :)
