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