What is an SBX file?
An SBX file is a project created by ScratchX, a development platform used to test experimental JavaScript Scratch extensions. It contains a Scratch extension project developed by Scratch users to allow the Scratch programming language to interface with hardware, such as the iRobot vacuum or LEGO EV3 robots, or web information sources, such as Amazon Text to Speech or Google Translate.
More Information
Scratch is an easy-to-learn programming language that helps young people develop games, animations, and interactive stories. There are several versions of Scratch, including Scratch 3.0 (.SB3 files), Scratch 2.0 (.SB2) files, and the original Scratch format (.SB files).
ScratchX is a project of the Lifelong Kindergarten Group at the Massachusetts Institute of Technology (MIT) Media Lab. It allows users to create, modify, and share experimental extensions that enable Scratch to connect and interact with external hardware or web information sources.

An SBX file may also be a SeqBox (Sequenced Box) container file created by SBXEnc, a program used to secure and back up a user's files in case of system failures, loss of partition information, or any other disk problems. It contains a file that has been encoded by the SBXEnc program. SBX files store information in a collection of blocks with each block consisting of a header, unique file identifier, checksum, block sequence number, and version.
More Information
The SeqBox format is designed to provide a safe archiving solution for securing and storing a user's files. The SBXEnc program is used to encode a data file to an SBX container and the SBXDec program is used to decode the SBX file back to the original file.
