What is a .sdb file?

An SDB file is a System Database file, primarily associated with Microsoft Windows operating systems. These files contain compatibility fixes and application metadata used by the Application Compatibility Database (AppCompat). AppCompat is a Windows component designed to ensure that older software runs correctly on newer versions of the operating system. SDB files store information about applications, including compatibility settings, shims (small pieces of code that intercept and modify API calls), and other data that helps Windows emulate an environment suitable for the application. They are crucial for maintaining backward compatibility and preventing application failures due to operating system changes. The data within an SDB file is structured and organized to allow Windows to quickly identify and apply the necessary compatibility fixes when an application is launched. These files are typically managed by the operating system and are not intended to be directly edited by users. Modifying SDB files can lead to system instability or application malfunctions.
