You have just experienced the "File System Redirection" of the Wow64. The
64-Bit explorer displays the content of the %windir%\System32 directory
where the 64-Bit binaries are stored, whereas the 32-Bit explorer displays
the contents of %windir%\SysWow64 where the 32-Bit binaries are.

May be you want to have a look at this Wow64 presentation:

Hi,
OK, Thanks, yes i understand,
i had a look to msdn....or anywhere at msft.

Now (on that) i have a new "meditation": If you have knowhow or
experience.....

-
if I do a backup, or an image, from *within Windows with an older 32bit-
version (older means available now)
i should have an eye on these folders.
-
might be (have not checked it) internal ntbackup will have either this or
that result, may be both...
-
further i guess i may have "64bit" results if i do a remote access (drive$),
or both ?
-
if i do an image for backup/restore, i am on good side, if i do it from
outside OS

any else ?

regards juergen

To my knowledge, current 32-Bit backup software will run in the Wow64 on x64
systems, and as a consequence, they will have file system redirection, which
means that they will show the contents of %window%\SysWow64 and present it
as being %windir%\System32. You should get a Windows x64 compatible version
of your backup solution from your software vendor.

x64 versions of Veritas and Atempo backup solutions should be available
shortly, as mentionned on this page:
http://www.microsoft.com/windowsserver2003/64bit/x64/app64catalog.aspx

Windows XP Pro x64 Machine comes with a 64-Bit version of NTBackup. This
means that NTBackup will show you woth System32 and SysWow64 directories,
and can backup/restore them.

A remote access to the whole disk through \\machinename\c$ shows the whole
filesystem, which means that you'll see both the
\\machinename\c$\Windows\System32 and \\machinename\c$\Windows\SysWow64\
directories

I guess so but I'm unsure. May be someone can have an more detailled answer
to this question.

Some information about "File System Redirection" in Windows x64:

Ghost 9.0 would copy the x64 image while running xp32 but after installing
the image it would corrupt. Retrospect 7.0 installs and functions properly
in x64.
