What is a SIX file?

SIX files mostly belong to Specialized viewer. An SIX file can hold different kinds of data. In some cases, it is a bitmap image file used on Atari ST/Amiga systems. The file stores raw pixel data in a simple, uncompressed format.
In other cases, a SIX file is used as a Siemens PLC program file. Here the file contains configuration data for HMI screens and is part of industrial control systems. More details are available at Siemens support.
There is also a use where SIX files serve as subtitle files. Such files hold text information that can be paired with media. A reference for this use is available at Wikipedia.

Note: Check the file's origin to know which format applies.

Tip: Always back up your file before trying different applications.

Tip: If the file's content is not obvious, consider using a hex editor or file inspection tool.

How to open a SIX file

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