/// Splits the given `&Path` into directory path (prefix) and file name (suffix).

/// # Arguments
/// - `path`: A referance to `Path` containing the path to be split.
///
/// # Returns
/// - `Ok((String, String))`: A tuple containing the directory path and file name as `String`s
/// - `Err(Box<dyn Error>)`: An error if the delimiter `/` is not found or the path conversion fails. Which means the path only contains file name.

/// - It wont check whether the path exists or not
