What is the .opt file that is created with the .cxp file whenever I save a project?


The .opt file stores the operating environment settings of CX-Programmer FA Integrated Tool Package. It is automatically created and saved when the project file is saved.

The .opt file saves the location and size of every window, and the symbols registered in the Watch Window while using CX-Programmer.

Deleting the .opt file will not affect the program, but the settings stored in the file will be reset to their defaults.
