.UVPROJX File Extension

A UVPROJX file is a project file created by version 5 of µVision, an IDE used to create programs for microcontrollers. It contains a definition of the project's structure, saved in XML format. UVPROJX files are used to open the related project's source code and other files.

Developers use the Arm Keil Microcontroller Development Kit (MDK) to create software for Arm Cortex-M based microcontroller devices. The MDK includes many tools, including the µVision IDE.

µVision allows developers to write microcontroller programs in C/C++ and assembly. They can then build, test, and debug their programs. Program development projects created in µVision are saved as UVPROJX files. These files contain XML-formatted data that tells µVision where the project's source code files and other files are saved, so it can load them correctly.

You can open a UVPROJX file in µVision (Windows). Doing so will open the µVision project the UVPROJX file describes. You can also open a UVPROJX file in Microsoft Visual Studio Code or any other source code or text editor, to view the XML data the file contains.
