To convert other file formats to the "Appliance Backup File" file type, you need software like Stormshield Network Security or a similar tool.
About NA files
A .na file primarily functions as a firewall configuration backup generated by Stormshield (formerly Netasq) Network Security appliances. IT administrators use these files to store, restore, or migrate security policies, network routing rules, and appliance settings. Interestingly, a significant number of .na files found in the wild are actually misnamed media files containing standard MP4 video, PDF documents, or JPG images. To open genuine firewall backups, users must import them via the Stormshield web administration interface or management console. Misnamed media variants can be opened with standard software like VLC media player for video or Adobe Acrobat Reader for documents - once the extension is corrected. Users typically struggle with .na files because the operating system does not recognize the extension by default. The genuine Stormshield backup format is highly proprietary and structured specifically for their hardware. It cannot be opened by standard text editors or web browsers, leaving network admins unable to easily audit the rules offline. If the file is a disguised video or document, the OS simply prompts an error, causing frustration for users who just want to view their downloaded content. For actual backups, extracting the internal data to TXT or XML is ideal for auditing, though standard converters fail at this. If the file is a misnamed media asset, the best action is extracting the container to its true format: MP4, PDF, or JPG. This file format is notoriously difficult to process because the authentic firewall backup is a closed, proprietary archive. Often, only the original hardware or software suite can properly read, apply, or export the data. Standard online converters completely fail to process it. Our system will inspect the file's internal signature. If our analysis detects a supported underlying or embedded format - like an MP4 video stream, a JFIF image structure, or a PDF header - viewing or conversion may still be possible.
Convert.Guru analyzes your NA file, detects the exact format, and lets you read the text inside.

The NA Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NA converter.
