Setting up - Link Plus has its own set of default paths to folders (e.g., Configuration, Export, Report) that are based off the C drive (e.g., C:\RegPlus\LinkPlus\Export). It really likes these paths. You will quickly find that you are forever copying directory paths to the actual location of these folders from Windows Explorer to Link Plus. To more easily navigate to your project's folders and make Link Plus projects portable:
