Sounds like a good deal to me. It also lets me back up 10 articles per folder from the Lotus Notes NSF file. I tested this tool on every version of HCL/Lotus Notes, that's fine.


Very easy to use tool to show data from NSF files without installing Lotus Notes application on your system. The software's graphical interface is truly impressive.


The perfect tool for a non-techy user. Excellent GUI helps me to operate this software on my own. Also impressed with the guys who supported me during the process.
