Python 2.7 and cmd on Windows 7 64 (files lost)

Thanks. 
You are right... but it is not enought.

This command:  echo %PROCESSOR_ARCHITECTURE%
give the statut:
   32:  x86
   64:  AMD64

and  DIR C:\Windows\System32\SoundRecorder.exe  is OK in 64, not in 32.



But if, in 64 mode, I copy SoundRecorder.exe to sr.exe, then I rename
sr.exe to sr.txt, the file (which is not an executable) is not visible 
in 32 mode.
And, if I move (or copy) sr.txt in an USB-drive, the file become visible 
in 32 mode !!!???

Therefore, Windows has a "trick" for mark the file like visible, or not,
in 32 mode. What trick?


OK, it is not a Python problem. 
Then... thanks again for your explanations.
