Softimage Image Format

SI can also refer to a Softimage Image file. Softimage was a 3D animation software that became famous for its character creation and effects. The file extension was primarily used to save digitally rendered images, including drawings, graphics and photos. You can open SI files of this type using Autodesk's SoftImage, but since this product has been discontinued in 2015, finding compatible software might be a bit tricky. A good alternative could be Adobe's Photoshop with a relevant plugin. Additional information about Softimage file history can be found on the Autodesk Knowledge Network, while plugins for Photoshop can be found on the Adobe's official site.

At times, the SI file extension can represent a PKCS#7 Signature file. This is a file format that is typically used to authenticate and secure data transmission over insecure networks, such as the internet. You can open these SI files using various programs that support PKCS#7 standards, such as Adobe's Acrobat Reader for a PDF with an attached signature. Details about the format can be found on Internet Engineering Task Force's official documentation.
