OpenFileDialog: Difference between FileNames and SafeFileNames

Question

For OpenFileDialog,
What are the differences between SafeFileNames and FileNames?

and Why is SafeFileNames is safe?

Answer 1

The answer is right there on the pages you linked. The "safe" filename doesn't include the path. Just the filename and the extension. The regular filename includes the full path.

The SafeFileName is safe because it doesn't expose the directory structure of your computer.
