File types

In the Project tree, files are marked with file type icons, for example clion icons fileTypes cpp, clion icons fileTypes h, clion icons CMake (see Recognized File Types for the full list with corresponding symbols). The 'question mark' icon icons fileTypes unknown indicates that CLion could not recognize the file type.

Source files

Files marked with blue overlay badges icons modules sourceRootFileLayer are source files (for CMake projects, if a file icon does not have this overlay badge, it means that the file is not included in CMakeLists.txt).

VCS status indication

If VCS integration is enabled for the project, CLion uses colors to denote VCS file status in the Project tool window. For the colors meaning, refer to File status highlights.

Structure, Hierarchy, and Breadcrumbs Icons

Elements in Structure View, Call Hierarchy or Method Hierarchy can also have visibility indicators: private icons nodes c private, protected icons nodes c protected, or public icons nodes c public.
