[python-win32] Not able to paste file in windows explorer using SetClipboardData

[game4 sale]

Hi,

I am trying to copy an image file to windows clipboard using my code and
paste it manually in any folder in windows explorer. I am using
*Windows 8* *64bit
*laptop, running *Python 2.7 *and *pywin32-218* for win32 APIs

I managed to paste my file in Wordpad application. But, i cannot paste
inside windows explorer. The Paste menu is disabled. Any help/suggestions
would be much appreciated.

Attached my code for reference.
