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 technically impossible. If you tried really really hard you *might* be able to convert a string that long into some kind of 4-digit integer checksum, but you would *never* be able to convert that back into a file path. Nor would it be guaranteed to be unique.
