require 'Win32API'

def get_long_win32_filename(short_name)
	max_path = 1024
	long_name = " " * max_path
	lfn_size = Win32API.new("kernel32", "GetLongPathName", ['P','P','L'],
'L').call(short_name, long_name, max_path)
	return (1..max_path).include?(lfn_size) ? long_name[0..lfn_size-1] :
short_name
end

short_name = 'C:\progra~1\frozen~1\frozen~1.exe'
puts "#{get_long_win32_filename(short_name)}" # => C:\Program
Files\Frozen-Bubble\frozen-bubble.exe
