Question

Quizplus · Accepted Answer

The correct function to use before deleting files and directories is file_exists(). This function checks if a file or directory exists and returns true if it does or false if it does not. Using the file_exists() function before deleting helps to prevent errors and unwanted behavior, as it allows the program to check if the file or directory actually exists before attempting to delete it. The other choices (B, C, and D) are not valid function names in most programming languages.
