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