If I rename a project file (say: test.uv2) to a different name (say: test.ct.uv2), KEIL still refers to the old project file. However, I could not observe any occurrence in the content of the new project file. This turns to a problem if I for example use the "find in files" feature in uVision3. Once I press OK, a dialog box shows up saying that it "Cannot write project file test.uv2", even though I am already using the new project file name. Therefore my question: How to remove all the dependencies which refer to the old project file name?
Note that there are two files that constitute a uVision project: project.uv2 project.opt
See: http://www.keil.com/support/man/docs/uv3/uv3_b_filetypes.htm
Maybe you need to rename both, or just delete the .opt?
You should also ensure that you delete all output files with the old project name - a full build won't necessarily do this for you.
Thanks, this solved the issue.
