Default project directory

Save files if the IDE is idle for N seconds

Save all modified files at regular time intervals.

Save files when switching to a different application

Save all modified files when you switch from IntelliJ IDEA to a different application.

Back up files before saving

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

Synchronize external changes when switching to the IDE window or opening an editor tab

Reload externally changed files when you switch to IntelliJ IDEA from a different application, or when you switch to the corresponding editor tabs.
