The version I sent to the list assumes a '/' directory separator. I'm releasing a fixed version (a snapshot of my working code) in a couple of seconds.

Thats fine on windows too (a backslash is only required on the standard command line, but everywhere else a / is ok too)

I do think it's worth a try, but I doubt NTFS is as good as ReiserFS :)

Mmmmm. I suspect NTs heavier file security checks will prove to be a significant disadvantage - benchmarks to follow.
