Microsoft's UF2 file format is used to distribute updates for various software products, including Windows, Office, and Visual Studio. UF2 files are essentially container files that hold update payloads, metadata, and digital signatures. While UF2 files are widely used, their internal structure and content are not well understood, making it challenging for researchers and developers to analyze and work with these files.
