from your home directory ../../../ = one level up from the cygwin root.

for example... if home is c:\cygwin\home\user then that relative path
would put you at c:\

the root (/) for cygwin is actually the cygwin directory (c:\cygwin)

if you're trying to get just on your c:\ you have to specify it as /cygdrive/c/
