The answer lies in . In large software projects, requirements change. A feature that demands a binary file (e.g., an optional language pack or a deprecated UI skin) might get cut from the final release, but its build script remains. To avoid breaking the build script, the developer creates a dummy file and labels it “useless” so that:
The term indicates that this file is not critical for core functionality. It is generated during a build process when a developer chooses to include “extra” assets—things like debug symbols, test data, or placeholder binaries that are not required for the final product. fg-optional-useless-files.bin
