Back up files before saving

Before saving the file, create a backup. If the save operation is successful, CLion deletes the backup. If not, it restores the contents of the original file from backup. This behavior is known as "safe write", and it prevents losing your file in case of a faulty save operation.

Sync external changes

Select the way in which the IDE will synchronize external changes:

  • When switching to the IDE window or opening an editor tab: reload externally changed files when you switch to CLion from a different application, or when you switch to the corresponding editor tabs.

  • Periodically when the IDE is inactive (experimental): reload externally changed files when the IDE is inactive for 15 seconds.
