Hi Lin,
I think you forgot to install the dokan library. The folder you
mentioned "c:\Python27\Lib\site-packages\fs\expose\dokan" contains
only dokan classes for pyfilesystem package, NOT the dokan.dll or
dokan.sys itself. Follow those steps:

1) Download and run -
http://dokan-dev.net/wp-content/uploads/DokanInstall_0.6.0.exe
(this will install the dokan lib for you)

2) Verify that dokan is installed - locate those two files after
installing dokan:
C:\WINDOWS\system32\drivers\dokan.sys
C:\WINDOWS\system32\dokan.dll
(if those files exist you have dokan installed successfully)

3) Try to run your script - "python.exe win_mount.py -d u -u URI:DIR2:......"

Let us know if it works for you.

I did check the library path and found the dokan library I have just installed through "python setup.py install". Below is the output of my try. Could you please help me find out what's wrong?
