When does the error occur?
TestComplete displays this message when you are trying to rename an existing feature file in your project, and your project is bound to a CucumberStudio project.
Why is the message shown?
TestComplete doesn’t support renaming feature files in bound projects because this might cause certain issues with synchronization between your project and CucumberStudio. See also Synchronize Scenarios.
Workaround
Log in to CucumberStudio, go to the project to which your TestComplete project is bound, and rename your feature file there.
When you synchronize the projects in TestComplete next time, the latter will import your changes to your TestComplete project.
