What is an SSU file?

SSU files mostly belong to Firmware Updater. SSU files are specialized firmware update packages used by satellite receivers and some software systems.
They contain binary data that updates the system firmware on devices. Manufacturers such as Novatek, Cheertek, and Supremo use these files to deliver improvements or fixes to hardware. In some cases, the content is compressed using GZIP and secured with encryption to ensure safe transmission and installation.
Key details as outlined by FilExt.com include:

Firmware Updates: They replace or upgrade the existing firmware in satellite receivers.

Data Files: Some SSU files act as containers for firmware upgrade data used by update utilities.

Encryption/Compression: Certain files use GZIP compression and encryption to protect the firmware code.

Vendor Specific Tools: Each manufacturer uses its own update utility. For example, visit the Novatek or Supremo websites for more technical details.

Alternative Uses: A few SSU files are also used in simulation software updates, as seen with Silvaco.

FilExt.com tip: To view or install an SSU file, use the appropriate vendor-provided firmware updater. Avoid manual modifications to prevent system issues.

SSU file format details:

To find out what program is needed to open SSU files, you need to determine the file format. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. Knowledge is power - this also applies when dealing with unknown or faulty files. Below is our analysis of the SSU files:

As a file extension, SSU isn't very common and includes various formats for various programs. But the following two file formats are common:

45% of all SSU files start with the bytes Novatek, which are crucial for this file format. They consist of illegible, cryptic characters. The files are often between 790 KB and 8 MB in size. It is a modern file type. The files contain the following words: Novatek, NT78320 and dr78326su_v30. 20180601_SU_SA_B1_2TUNER_2GB_OPTMO_FANTASIA.ssu is a typical file name. Files like these are sometimes connected to fantasia, tuner, optmo, navi and optimo.
10% of all SSU files use the same file format, which can be identified by the letters "Cheertek" at the beginning. If you open these files in a text editor, you will see only illegible characters. The files are on average 320 KB in size and range from 130 KB to 1 MB. Certain words are almost always found in the files, such as 01.00/08, CT216S, Cheertek, dr216s_v30 and ctdb. Some examples of file names are userdb.ssu or defdb.ssu.

The remaining 45% of all SSU files are files with no common format, often, for example, GZIP and supremo. These files are often connected to supremo, demo, ppdk, simucad, logic, company, silvaco, analog, legend or tank.
