What is a WXS file?

Source file created by Windows Installer XML (WiX) toolset, a Windows installer developing program; XML document containing one root element (<Wix>); a collection of strings for localizing a product into a specific culture; similar to .CPP files.

More Information

WXS files must be written in WiX schema or else they will not compile. The <Wix> element is a top-level container in the WXS file, it can include the following children:

  • PatchCreation - Compiles into a .PCP file.
  • One of the following elements:
    • Bundle - Creates bundle packages.
    • Module - Compiles into a .MSM file.
    • Patch - Compiles into a .MSP file.
    • Product - Compiles into a .MSI file.
  • Fragment - Helps build an installer database in WiX.

There can only be one <PatchCreation>, <Product>, <Module>, or <Patch> section element for each WXS file or else the linking process will be broken. There can be an unlimited amount of Fragments.

NOTE: WiX Source files are preprocessed and compiled into .WIXOBJ files by the Candle tool in the WiX Toolset.
