Without involving some kind of lookup table/map service to store the paths =
(which would entirely defeat the purpose) what you are ranting about is tec=
hnically impossible.  If you tried really really hard you *might* be able t=
o convert a string that long into some kind of 4-digit integer checksum, bu=
t you would *never* be able to convert that back into a file path.  Nor wou=
ld it be guaranteed to be unique.
