Code Composer Studio (CCS) is based on the Eclipse open source software framework. When executed for the first time, select a workspace, where all projects will be placed. A workspace is a directory that holds all elements (projects, links to projects, possibly source code) used in the development. Every time CCSv5 is executed, it will ask for the workspace directory. If using a single directory for all projects, just check the option Use this as the default and do not ask again. The workspace can always be changed later from inside CCS. Inside the workspace, projects reside - All work on Code Composer Studio is based on projects - a collection of source, include and configuration files.
