The single-user project is for individual designers who do not share files. It is the default project. For this project type, we recommend that you make the workspace local to your computer. The project file (.ipj) is stored in the workspace.
All design files are in one workspace folder and its subfolders, except for files referenced from any number of libraries. You create and edit files in the workspace. It is not necessary to check files in and out for editing.
The file status browser is not available because you are the only person with access to the files.
