B. File Types

The following file types are supported by µVision:

Project Files

• *.OPT: Project Option file with options (debugger settings, current open files, screen positions, and so on) from older µVision versions. This file is read and transformed into a *.UVOPT or *.UVOPTX file type by µVision.
• *.UVGUI[.user-name]: µVision4 Project screen layout file. The extension [.user-name] is added when working in a work-group environment. When this file is missing, the default layout is used. This file is not mandatory.
• *.UVGUIX[.user-name]: µVision5 Project screen layout file. The extension [.user-name] is added when working in a work-group environment. When this file is missing, the default layout is used. This file is not mandatory.
• *.UVMPW: µVision4 Project file for Multiple Projects. Contains references to other project files and binds them into one project. The file is mandatory when multiple projects are grouped into one project. Has an XML structure and can be shared in a work-group.
• *.UVPROJ: µVision4 Project File. Contains the project structure in XML format. This mandatory file can be shared in a work-group.
• *.UVPROJX: µVision5 Project File. Contains the project structure in XML format. This mandatory file can be shared in a work-group.
• *.UVOPT: µVision4 project options. Contains the settings for the debugger, trace configuration, breakpoints, currently open files, ... . This mandatory XML file can be shared in a work-group.
• *.UVOPTX: µVision5 project options. Contains the settings for the debugger, trace configuration, breakpoints, currently open files, ... . This mandatory XML file can be shared in a work-group.
• *.UV2: µVision3 Project File. Open the files with a later µVision version to convert the file to a new project type.

Object and HEX Files

• *.(no extension): Absolute Object File (executable programs generated by the Linker).
• *.AXF: Absolute and executable object file generated by the Linker.
