What I picked up from this semi off topic thread is, that the particular
distinction is utterly irrelevant, and the only portable (in Java's sense)
way to do file-name manipulations would be to wrap the original name in a
File object, and stick to File methods as much as possible, turning back
to a String only at the end of all the jugglings.

If portability means merely "runs on Windows and various unixoids", then
File.separator is at least better than "\\".
