Norton FileSaver is a component of Norton Utilities for Microsoft Windows. A .pnfv file stores volume data used by FileSaver.
The format is specific to Norton Utilities and is not a general-purpose interchange format. It is a legacy utility data format, so current general-purpose applications are unlikely to recognize it.
Open a .pnfv file with the Norton Utilities installation that created or manages it on Microsoft Windows. FileSaver may use the file as part of its own volume data rather than opening it as a separate document.
Do not edit the file with a text editor.
A .pnfv file cannot normally be converted meaningfully with a standalone converter because it contains Norton FileSaver volume data, not a document in an interchangeable format.
Retain the file with the associated Norton Utilities data if it is needed by FileSaver.
