NSF (Notes Storage Facility) is a database format linked to the now-discontinued IBM Notes service. Its purpose is to store emails, documents, forms, etc. Users with NSF emails might wonder what is to be done with their data, considering the state of IMB Notes, but that answer is easy — file conversion.
Cigati NSF to PST Converter is a straightforward tool designed to help individuals migrate their NSF mails to PST, as the name says, but also to a plethora of other formats like EML, MSG, EMLX, PDF, PST, HTML, MHT, MBOX, CSV, and more.
The app's interface is nothing to be intimidated about. Even if this is your first time converting files, the layout should be intuitive enough to properly guide your steps. Processing files is done by either single items or by bulk. Load up a folder with NSF items, choose the output format and location, and the rest is taken care of.
Removing duplicates is also a possibility with this particular tool. If your email database has duplicated items, in order to save storage space and provide a clean conversion. Furthermore, the program should be able to remove encryption for NSF files. If you have protected NSFs, use the Remove Encryption feature to drop their defense before migrating them.
All in all, Cigati NSF to PST Converter looks like solid support for NSF owners who wish to migrate their emails to more common formats.
