How can I preview the vsd(microsoft visio) file?
It is needed in my groups.Thank you.

Now I think there's no installed conversor from visio to pdf ( that's what really is neaded to preview visio document ). If you want it you could try implementing your own conversor ( not much complicated, but needs some time ) or talk with us to implementing it http://www.openkm.com/en/contact.html
