I am not sure of what you are trying to do here. If you are renaming the project's directory name, I would try:
1) Make a backup copy of your project directory.
2) In the IDE, choose Project > Reset Entry Paths
3) Quit the IDE.
4) Rename the directory.
5) Open the renamed directory folder and double-click on the project file.
6) Choose Project > Re-search for Files.
That might do it. I'm downloading a copy of the Classic tools right now (got to get those latest updates) and this is from memory. Also, make sure that you do not have any absolute paths (for example, C:\My_Project\My_Custom_Headers) in your project. If you do, you need to change those to project relative paths or edit them.
please refer this message:

I thnik if I can change the %projectFileDir to my new project paths, the trouble will be solved. So this is why this message is post.
You can change file directory paths in the IDE through the Access Paths panel. In the IDE, choose Edit > Standard Settings > Access Paths. At a minimum, you can add the directory as a user path and force the IDE to search all user paths.
Looking at the screenshot, the other thing to consider is that the directory path is miles long and something might be choking on that length. Specifically, something in the debugger software and not the IDE, since it is building the program.
