Opening and Reopening Files in the Editor
Opening files for editing
The maximum size of files parsed by CLion is controlled by the
idea.max.intellisense.filesize setting in
idea.properties file located in the
bin directory of the CLion installation folder should not be edited. Instead of editing the original
idea.properties file, create an
idea.properties file in the following location, open it for editing and add the required properties:
- For Windows:
- For *NIX:
- For macOS:
Note that the larger the file is, the slower its editor works and the higher overall system memory requirements are.
To open a file for editing, do one of the following:
- Double-click the desired file in one of the tool windows.

If the file type is registered, the file opens silently in CLion's editor.
If the file type is registered under the category Files opened in associated applications, it will be opened in its associated application, rather than in the CLion editor. By default, CLion suggests a number of such file types, for example
If the file type is unknown, CLion suggests to choose whether you want to register a new file type, or open such file in its associated application. Specify your choice in the Register New File Type Association dialog box:
You can register the required file types on the File Types page of the Settings/Preferences dialog.
