The easiest and fastest method to convert mutiple nsf files is to use a nsf tool which aids in mutiple processing of nsf files. We have currently taken up a project to convert 1100 (Approx) files of one of our client and we used "Export Notes" from
http://www.convertnsftopst.net and works great.
The technical support was awesome and much appreciated. The tech guy "Evan" was very helpful.
I wish other's could also offer a same tehnical helpdesk so as to help users like us.
This is just to share my experience with needy users in search for a good tool.
