There doesn't seem to be any changes since it was first introduced in 
Windows NT 3.1.

Depends on how the file is copied. The shell including Windows Explorer, 
are ADFS aware and will presere them when copying. Windows API that can 
copy file in a single function are mostly ADFS aware. Such as 
SHFileOperation, CopyFile, and CopyFileEx. Manual file copy using 
FileOpen, FileRead, FileWrite, etc. are not ADFS aware as they 
specifically chose which stream to access when opening the file. Note 
that in Windows, ADFS is strictly NTFS only. ADFS will not be preserved 
when file is being copied accross network since the system do not have 
control over the internal file-system of the storage on the other side of 
peer. There is no Windows API specifically for this and only by client-
server based custom program these can be achieved. Check the MSDN library  
for each file function you want to use for any limitation.

For ADFS, no difference.
