The '''Scratch 1.4 File Format''' saves projects in version 1.4 of the [[Scratch]] programming language, a language designed to teach programming to young children. Since the program code consists of graphical tiles rather than text-based source code, a binary format was used to save it, along with the associated objects which form part of a program project.

Scratch projects are stored in files with a '''.sb''' extension. They start with a 10-byte header containing the [[ASCII]] characters ''ScratchV02''. Multi-byte numeric values within the file are stored in [[Endianness|big-endian]] fashion.

A sprite file, with the extension '''.sprite''', stores a sprite along with related variables and lists, in a format similar to the project file but without the header at the start.

Detailed documentation can be found in the Scratch wiki.

The [[Scratch 2.0 File Format]] switched to the use of [[ZIP]]-compressed [[JSON]].
