 As I've said in my problem report, the best solution for me is to write a 
 system utility to deal with ntfs attributes (and ads). You can use in 
 that utility the format that windows uses in its programs, with ':' as a 
 separator. You can use in the implementation of that program the idea of 
 J. Hannken to parse for colons from the end of the name, so you can keep 
 naming your files without restrictions.
 Using ^G is a dirty hack that allow me to read files without restrictions, 
 and the same time access the attributes without any problems.

 Yes, and case insensitive file names. So NetBSD must use case insensitive 
 file names in ntfs? And use '\' for paths in ntfs because window uses

 Because is UNIX, and the file system permits the use of unicode characters 
 except '\' and '\0' in posix sytems.
 If an OS has restrictions in its file names, is that OS who has to deal 
 with it. As long as the file system permits it (and doesn't matter who 
 develop the file system) other OSes don't have to be tied to others 
 There is other restrictions in windows names apart of the use of some 
 characters. A lot of them. Do you think is a good idea to put these 
 restrictions in the ntfs implementation?

 I hope you have tested that, because if not, you are just trolling

 - Every OS that uses ntfs-3g, for example NetBSD?
 - Tuxera NTFS (a comercial version from the ntfs-3g developers)
 - Linux ntfs driver.
 - Someone with a Mac can test the internal (unstable) driver, I don't know.
 I said "Do whatever you want", but nevertheless, I'm now going around 
 things I already have said and looking for a stupid windows machine to 
 test file names with colons...
