Correct, once you have the option "Hide extensions for known file types" unchecked, you should see the filenames with the extensions behind them.

The two files will be renamed exactly:
AUTOINSTALL.CMD -> AUTOINSTALL.CMD.BAK
DISKPARTSCRIPT.TXT -> DISKPARTSCRIPT.TXT.BAK
on the recovery image.

If you are changing the "Hide extensions for known file types" option in Windows 7, you may not have known that pressing the 'Alt' key revealed the menu bar, which is by default hidden in most Explorer Windows.

Good luck, hope it works out.
