Compressed archive created with the NZip file compression program
File type:
An .nzip file is a compressed archive created with NZip. Like a ZIP archive, it can contain one or more files and folders in a reduced-size package.
Use NZip to open, extract, and create NZIP archives. Compatibility with general-purpose archive utilities depends on whether the archive uses a standard ZIP structure or NZip-specific features.

NZIP archives are intended to combine multiple files and folders into a single compressed file. Compression can reduce storage requirements and make groups of files easier to transfer or distribute.
The format is associated with the NZip program, which creates and extracts files with the .nzip extension. The exact compression method, metadata, and archive features depend on the version of NZip used to create the archive.
On Windows, the most appropriate software is the original NZip application. Some ZIP-compatible archive managers may be able to inspect or extract an NZIP file if it follows a compatible archive structure, but this should not be assumed for every file.
There is no broadly established native NZIP support on macOS or Linux. Users on those platforms may need to run NZip through a compatible environment or use an archive utility only if it recognizes the file. Always verify extracted files after using third-party software.
To open an NZIP archive, install or locate the NZip program, then open the file from within the application or use the file's context menu. Choose an extraction command and select a destination folder.
On Windows, use NZip first. On macOS or Linux, try a ZIP-compatible archive manager only when it identifies the file correctly; otherwise, use NZip in a compatible Windows environment. Do not rename the extension unless the archive utility confirms that the contents use a standard ZIP format.
To convert an NZIP archive to another archive format, open it with NZip, extract its contents to a folder, and recompress those files with a utility that supports the desired format, such as ZIP or 7Z. This preserves the contents but may not preserve NZip-specific metadata.
To create an NZIP file from another archive, extract the source archive first and then add the extracted files to a new archive using NZip. Online conversion services may not recognize NZIP files and should be used cautiously, especially for confidential data; a desktop tool is generally safer.
