//Question 4 - Filesystem & args  

// Task: Implement the code as described in the main body, make sure to handle cases when the requested file is not found or the "files" directory doesn't exists and you have to create it
// Prefer modern solutions over classic C style solutions and keep in mind that this code should be able to run in other windows, linux and other platforms (hint: '/' and '\' in file paths)
