A CUIx file that is typically controlled by a CAD administrator or manager. It is often accessed by many users and is stored in a shared network location. The file is read-only to users to prevent the contents in the file from being changed. Often, a CAD administrator or manager creates an enterprise CUIx file by modifying the program's default main CUIx file, and saving the file to a shared network location. Users then specify this file in the Options dialog box.
An XML-based file that stores customization data for products starting with AutoCAD 2006-based products and ending with AutoCAD 2009-based products. The CUI file was replaced by the introduction of the CUIx file. A CUI file can be converted to a CUIx file using the Transfer tab of the CUI Editor (CUI command).
