File used by ESRI ArcGIS Desktop GIS mapping software; contains a spatial index for a .SHP shapefile; used to optimize queries and reduce the overall time spent accessing multidimensional object shape information.

SBX files are optional when specifying a shapefile. However, shapefiles without spatial indexes may suffer from slow loading and rendering times.

Compressed archive created by Shoebox, a tool included with the GLBasic software development toolkit; can store application resources such as graphics, video, music, or data files; can be decompressed by the application at runtime to extract specific files.

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.

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 allows users to create, modify, and share experimental extensions that enable Scratch to connect and interact with external hardware or web information sources. To open an SBX file in the online MIT ScratchX editor: Open the Scratch project editor on the MIT ScratchX webpage. Select File → Load Project in the browser window. To create an SBX file in the online MIT ScratchX editor: Open the Scratch project editor on the MIT ScratchX webpage. Create your project and select File → Save Project. Name your file, choose the save location, and click Save. NOTE: ScratchX is a project of the Lifelong Kindergarten Group at the Massachusetts Institute of Technology (MIT) Media Lab.

An SBX file is 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.

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.
