I don't know if and how it apply and can be of any help here, but in my
C programs in the very past after switching from DOS to Windows long
names a following trick solved often my problems with too long names:
step 1: setting the current directory to the beginning part of the
name with a length which can be passed as a function parameter
step 2: usage of the remaining part of name as name passed as
parameter to the file accessing function (relative to current directory)
