Thank you for sending me the link. I tried it by copying the
“shortcut_target(filename)” function into my script. But it does the
same thing as I had mentioned in my previous e-mail. i.e It returns me
the target path correctly if the target exists physically in my hard
disk, but behaves in a wrongful manner if I delete the target keeping
the shortcut intact (Broken shortcut). In that case it creates an empty
file (0 size) with the same name as that of the existing target &
creates it at the same physical location where the target was existing
before. Looks like a bug in this function.
Well I'm not seeing that behaviour at all. Is it possible that
something else in your code is having this effect? I'm on
Win7 x64 Python 2.6.6 pywin32 216

link = pythoncom.CoCreateInstance (

pythoncom.CLSCTX_INPROC_SERVER,
shell.IID_IShellLink
)
link.QueryInterface (pythoncom.IID_IPersistFile).Load (filename)
#
# GetPath returns the name and a WIN32_FIND_DATA structure

name, _ = link.GetPath (shell.SLGP_UNCPRIORITY)
return name
