What is an ST7 file?

ST7 files mostly belong to Strand7. ST7 files have specific roles that depend on the context in which they are created.

Strand7 model files: These store data for engineering simulations. They keep details like geometry, material properties, and load conditions used in finite element analysis. Use Strand7 software to view or edit these models.

ST-7 compressed image files: These hold image data from SBIG CCD cameras. The files use a compressed format for storing raw data from astrophotography, and they are handled by SBIG CCDOPS. More details are available at this webpage.

FilExt.com tip: The file extension is context-specific. To work with an ST7 file, check its creation source and open it using the correct software.

How to open ST7 files
