wxi

wxi is a short sequence that can denote different things in different contexts and does not have a single, universally accepted meaning. In computing, it is most commonly associated with the Windows Installer XML (WiX) toolset, where it is used as a file extension for include files.

Files with the .wxi extension in WiX contain fragment definitions that can be reused across multiple installer projects. A .wxi file typically stores reusable components, UI patterns, or configuration blocks that are included into one or more .wxs source files. This modular approach helps maintain consistency and reduces duplication when building Windows Installer packages.

In other contexts, wxi may appear as an acronym, code, or filename in domains outside WiX. Because it is not tied to a unique meaning, its interpretation depends on the domain, project naming conventions, or documentation. When encountering wxi, look for contextual clues such as accompanying file types, project names, or standards references to determine its intended sense.
