Project tool window
The Project tool window lets you take a look at your project from various viewpoints and perform different tasks such as creating new items (directories, files, classes, and so on) , opening files in the editor, navigating to the necessary code fragments, and more.
By default, the Project tool window shows your current project root.
Most of the functions in this tool window are accessed as context menu commands in the content pane and via associated shortcuts.
Also, the view contains the Scratches and Consoles folder that lets you manage created scratch files and extension scripts.
Views
You can use Project tool window to view your project tree or a certain scope of files:
Project view. This view displays all the project items along with their dependencies (SDKs and libraries) .
Scope views (Project Files, Open Files, and so on). These views display the contents of the predefined and user-defined scopes.
The elements of the views are highlighted following the scope-color associations defined in the File Colors dialog and the scope-associated overlay icons.
You can also display each view in a separate tab: click 
and disable the Group Tabs option.
Preview files
There are two ways to preview files without opening each one in a separate tab:
Use the file preview popup: select a file in the Project tool window and press Space.
Enable the preview tab: click
and select Enable Preview Tab.
Show file size and modification timestamp
You can view the size and modification timestamp for the files in the project tree.
Select from the main menu.
Show tree indent guides
In the Project tool window , you can display vertical lines that mark indent levels and help you better understand the hierarchy of the components in your project.
Go to
Set the Show tree indent guides checkbox.

File status highlights
If VCS integration is enabled for the current project, CLion uses colors to denote VCS file status in the Project tool window.
You can configure VCS file status colors on the Version Control | File Status Colors page of settings Ctrl+Alt+S.
The table below lists default file status colors and their meanings in some of the color schemes.

To each scope, you can assign its own color. For more information, refer to Associate scopes with colors.
