• Current directory is used by default
• File name and size are also displayed by default
• /b (bare) switch is available to list MD5 hashes only. Files are still processed in Alphabetical order (case ignored).

• Recursively process subdirectories (/s)
• Quiet mode (/q) - do not print failed attempts (ex.: no access rights to a file)
• Flexible/configurable output (templates: MD5 hash, file name, file size, directory name, directory path)
• Handle "no permission" directories
• Add tests!
