Hi Eliot Moss,
Thank you very much for the quick response & the information.It really helped.
I just set 'CYGWIN=winsymlinks:lnk' & I am now able to open sym-link
file. Both 'CYGWIN=winsymlinks:lnk' & 'CYGWIN=winsymlinks' are working
for me.
But it creates a shortcut(not the regular file). Hope it won't impact
my existing setup.

But both  'CYGWIN=winsymlinks:native' (which is default I believe) &
'CYGWIN=winsymlinks:nativestrict' are not working for me. Just to
understand, In what OS environment/File System 'native' will work?

Regards
Vinay Hegde
