     <p>A Scratch project has three main components that can be "corrupted" in different ways.</p>

       Scratch project files are zip files.
-      The zip file can often be corrupted by a storage device failure, for example due to a power outage or not ejecting a USB drive before unplugging.

       Scratch and most other tools that open zips don't know how to handle corruption.

-      Depending on how bad the zip is corrupted, sb3fix might recover your project in its entirety or may miss significant parts.

       This file contains your project's sprites, scripts, variables, lists, and metadata about costumes and sounds.
       When you load a project, Scratch checks that all parts of the JSON are in the correct format.
       There are bugs that allow the project.json that gets generated when you save your project to not pass these checks.

       This usually results in your whole project being recovered, and writing new fixes is usually easy when we become aware of missing fixes.

       There are other bugs that can result in these symptoms even if the asset is not corrupt.
       Some corrupted costumes load fine but cause a crash if you try to edit them.
       At this time, sb3fix does not attempt to fix asset corruption beyond our attempts to fix zip corruption.
