The .via file extension is associated with µVision4, an integrated development environment from Keil for creating programs for ARM-based systems.
A .via file stores data used by the ARM source-code compiler during development and compilation. It is a support file for the compiler rather than a source-code file or a finished program.
The format is intended for use with the Windows version of µVision4 and is normally handled as part of the development project.
Open the project containing the .via file in µVision4 on Microsoft Windows. The file is normally used automatically by the compiler and is not intended for standalone viewing or editing.
A .via file does not normally have a useful standalone conversion. It is compiler support data, so it should generally be regenerated by building the associated ARM project in µVision4 rather than converted to another format.
