File type: Various data file
A .nw4 file is a legacy data file associated with Novell NetWare 4.x, the network operating system for Microsoft MS-DOS systems.
File type category:
Various data file
Date updated: September 27, 2026
Novell NetWare 4.x used .nw4 files for data associated with the NetWare 4.x environment. The extension identifies a NetWare data file rather than a general-purpose document.
The exact contents and purpose depend on the NetWare component that created the file. NetWare 4.x is a legacy product, so .nw4 files are generally encountered only in older NetWare installations or archived system data.
Open a .nw4 file in the original Novell NetWare 4.x environment on Microsoft MS-DOS, using the NetWare component that created it. It is not normally intended to be opened as a standalone document, and changing it with a text or binary editor may make the associated NetWare installation unusable.
If the file belongs to an active or recoverable NetWare 4.x installation, use the relevant NetWare utility to export or migrate the data; otherwise, preserve the file with the original system data.
