Opening a SUN File

The SUN file type is primarily associated with Opera PMS / X11 Viewer.

SUN	File extension: SUN
	File type:	business transaction log file

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.

SUN file format details:

Each file has a definite file format, that is, how the stored data is arranged in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the SUN files is as follows:

SUN is rarely used as a file extension and is used by a few programs, each with its own file format. The two most popular formats are as follows:

35% of all SUN files have the same signature eyJwcmVsaW1pbmFyeVJldmlldyI6eyJjdXJyUGFnZSI6MSwibG. These files are text files, so they contain words and text. The average file size is 13 KB with most files being between 5 KB and 24 KB in size. The file type was created recently. Certain words are almost always found in the files, such as bXNpZCI, eyJwcmVsaW1pbmFyeVJldmlldyI6eyJjdXJyUGFnZSI6MSwibGlzdCI6W3siYnVz, NvcmRlcm, bGFjbGFzc, vIjoiMSIsImZvcm, bWUiOiLlvaLlvI/or4TlrqEiLCJmb3JtdWxhY29kZSI6Ij and bWUiOiLotYTmoLzor4TlrqEiLCJmb3JtdWxhY29kZSI6Ij.
20% of all SUN files start with the magic bytes VERSION, which are always the first bytes of this file format. The contents of these files are easily readable with a text editor. SUN files can be up to 250 KB in size, but are often around 820 bytes - 160 KB. Certain words are almost always found in the files, such as VERSION 42601 and MFRV. Some examples of file names are KW_RV20180601.sun or NM0011_RV20180601.sun.

The remaining 45% of all SUN files are different files with different signatures, frequently e.g. Sun Raster bitmap and SUNTronic module. They are often associated with tfevents or events.
