Doxygen command \file takes a file path as an optional argument. By default, the input file path is used. It is good practice to leave the optional argument blank to avoid conflicts. For example, command `\file initialize.cpp` in file `/src/core/initialize.cpp` will trigger a warning because 14 files in the project are named `initialize.cpp`, while `\file src/core/initialize.cpp` won't trigger a warning, but it must be updated everytime the file is moved or renamed. Providing a file path is only necessary in specific cases, for example when C++ files are generated with a script via `FILTER_PATTERNS`.
