FWIW "good" Windows applications should be able to read/use 32,767
character paths but only write 260 character paths. Unfortunate as it
may be, a great many applications use the MAX_PATH macro has a hard
upper limit so cannot read longer paths, additionally many of Windows
built-in tools fail to handle long paths correctly - most significantly
Explorer (making it difficult to deal with long paths correctly at all).

Just thought it was worth saying.
