CLion 2018.3 Help

Open, Reopen, and Close Projects

CLion lets you open several projects simultaneously in different windows. By default, each time you open a project while another one is opened, CLion prompts you to choose whether to open the project in the same window or in a new window. If necessary, you can change this behavior using controls on the System Settings page.

In the Project Opening section of the System Settings page, choose one of the following options:

  • Open project in a new window to open a new CLion window each time a new project is opened.

  • Open project in the same window to stay in the same CLion window.

  • Confirm window to open project in to keep the default behavior and display a dialog box to choose how to open each new project.

Opening projects

This operation refers both to the projects created in CLion, and the projects from existing sources.

Open a project

  1. Click Open on the Welcome screen or File | Open on the main menu.

  2. In the Select Path dialog box, select the directory that contains the project to open.

    Note that if you open a CMake project, it must contain a CMakeList.txt file. Otherwise, the project will open but no coding assistance (i.e. code completion, navigation, intention actions etc.) will be available.

  3. Specify whether you want to open the project in a new frame, or close the current project and reuse the existing frame.

Open a project from the command line

  • At the command prompt, type:

    <CLion> <path_to_the_project folder>

Reopening recent projects

CLion keeps the history list of the recent projects, from which you can select the desired one.

When CLion starts, the most recent project reopens by default (unless this option is disabled on the System Settings page of the Settings/Preferences dialog (Ctrl+Alt+S).

Reopen a recent project

  • Click Open Recent on the File menu and select the desired project from the list.

  • Invoke the Run Anything dialog by pressing Double Ctrl (or search for Run anything in Help | Find ActionCtrl+Shift+A). In the Run Anything dialog, type Open to see the list of recent projects:

    open recent project from Run Anything

  • On the Welcome screen, click the project of interest in the left-hand pane where the list of your recent projects is shown. Start typing in the Welcome screen to filter the list of recent projects.

Remove a project from the list of recent projects

  • Click Open Recent on the File menu, then click Manage Projects at the very bottom of the recent project list.

  • Click the closing icon for the project to remove. The selected project will be removed from the list of the recent project in the Project window and on the Welcome screen.

To remove a project only from the list on the Welcome Screen, right-click the target project and select Remove Selected from Welcome Screen.

Closing projects

When the only open project is closed, the Welcome screen is displayed. In case of multiple projects, each one is closed with its frame.

To close a project

  • On the main menu, click Close Project on the File menu.
