--- title: Widgets - project inspector --- ### Project inspector The project inspector is used to - select the project configuration. - open sources in an new editor. - add or remove source if the active project has the [CE format](features_projects). ![](img/project_inspector.png) The toolbar buttons are only activated for CE projects. - ![](https://raw.githubusercontent.com/BBasile/Coedit/master/icons/file/document_add.png): Adds a D source to the project from a dialog. The new source is not directly opened in the editor. To add a file that is already edited, rather use **"Add file to project"** from the **File** menu. - ![](https://raw.githubusercontent.com/BBasile/Coedit/master/icons/file/document_delete.png): Removes the selected source (selected in the widget tree, not in the editor) from the project. - ![](https://raw.githubusercontent.com/BBasile/Coedit/master/icons/folder/folder_add.png): Adds a folder of D source to the project from a dialog. The procedure is recursive. Note that instead of using the dialogs to add files, it's also possible to drop items from a file explorer.
