For what it's worth, this morning I also tracked my serialization errors down
to this same cause. Apparently, NTFS allows every path component to be 255
characters but Windows only allows a _total_ path length of 279 characters.

I read in another post about long URLs a suggestion from William about using
the DOS 8+3, ISO9660, or remapping options to control this.  

This is workable for me -- especially ISO9660 -- except that I need some way
of mapping the original urls back to the mirrored structure. Does HTTrack
currently offer an option to log the remapped path/name along with the full
path/name? If not, I'd propose/request adding that option as a good solution.
