Manually edit .jpn files in How Do I? Posted February 24, 2010 · Report reply Hi, JetPackII projects should not be modified manually. JetPackII uses relative paths if possible (relative to the project root directory within one disk). The solution may be to create a script that copies the jpn project files to the root project directory, build the package and then delete the project file. Is it suitable for you? We plan to solve this limitation (relocation of jpn projects) in the next version of Excelsior JET.
