Moving Projects
Wing's project files reference the files and directories that were added to the project by using relative paths, which it interprets from the location of the project file.
If you need to move a project file to a new location relative to the location of the files and directories it references, without also moving those files and directories, use Save Project As... in the Project menu. This will update the relative paths so that the project will continue to work from its new location.
If you just want to rename your project, you can also use Save Project As... to write it to a new name, and then remove the old project files after you are no longer using them.
