         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 badly the zip is corrupted, sb3fix might recover your project in its entirety or may miss significant parts.
