Non-Project Files Protection dialog
This dialog appears when you try to edit non-project files (e.g, library sources, external sources and so on), and protects them against accidental modifications.
These files do not belong to the project
This area displays a non-project file that you are trying to edit.
I want to edit this file anyway
Select this option to disable protection for the listed files.
I want to edit all files in this directory
Select this option to disable protection for the listed files and all files in the same directory.
I want to edit any non-project file in the current session
Select this option to disable protection completely.
All options are effective during the current session, once the IDE is restarted, protection will be re-enabled. Also, you cannot change your decision for a particular file within the current session.
