If you wanna see ugly, add this to your list of possible holiday destinations:

I don't know if this'll work on cygwin.
On native Win98+, it expands the full path.

#------------------------------------------------------------------------
require 'Win32API'

GetLongPathName = Win32API.new('kernel32', 'GetLongPathName', 'PPL', 'L')

f_short = 'D:\PROGRA~1\BORLAND\CBUILD~1\PROJECTS\CONNEC~1\CONNEC~1.CPP'
f_long = "\0" * 260
flen = GetLongPathName.call(f_short, f_long, f_long.size)
puts f_long[0, flen]

#------------------------------------------------------------------------
