Description

This version of the code uses the ? operator to propagate any error that occurs during the call to fs::remove_file. If an error occurs, it will return an Err variant with the error value, which will be logged as a warning message by the caller. If the file is successfully deleted, it logs a trace message and returns Ok(()).

Motivation and Context
