What is a SUN file?

SUN files mostly belong to Opera PMS / X11 Viewer. SUN files can mean two different things depending on the source of the file.
  • Opera PMS Transaction File: This file is used by the Opera PMS system and is also known as the Micros Opera Sales Journal. It holds transaction records from a point‐of‐sale setup. Only the specialized Opera PMS software can correctly read and process this data.
  • X11 Sun Raster Image: This file is a bitmap image that follows the Sun Raster format used in Unix/X11 environments. It contains a header with image metadata and the pixel data that makes up the picture. Many image viewers or editors that recognize Sun Raster files can open it. For more details, see this page.
    • FilExt.com tip: Because both types share the SUN extension, using a hex or file inspection tool to check the header can help determine which kind you have.

    How can I open a SUN file?

    You need a suitable software like Opera PMS / X11 Viewer to open a SUN 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 SUN file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a SUN file directly in the browser:. Just drag the file onto this browser window and drop it.
