Richard,

Have you tried using SHFileOperation? The FOF_NOCOPYSECURITYATTRIBS
flag implies that the default operation would copy the security
settings - though I've never tried it.

CopyFile/CopyFileEx will not preserve the file's security.

As David said, SHFileOperation may meet your needs. If not, then you would
have to call GetFileSecurity to get all of the info out of the source
file's security descriptor, use it to build a new SD, then copy the file,
and finally, apply the new SD to the file via SetFileSecurity. This is a
fair amount of work as you have to get and set all the types of info out of
the SD (owner, DACL, SACL, etc). You will need the restore privilege to
call SetFileSecurity to set the OWNER_SECURITY_INFORMATION to any user
besides the one your app runs in. Normally, backup operators have this
privilege, but normal user accounts don't.

And, in addition to what Dan mentioned, if your NTFS partitions are on separate
servers and you are moving the files between WinNT v3.5x/v4.0 and either
Win2K/XP then you have to deal with the different manner in which inheritable
ACEs are handled on those operating systems.
