Protecting the Stage folder against unwanted Changes on Windows
It is highly recommended to protect the Stage folder, subfolders, and files against unwanted changes. Custom levels should therefore be saved in a separate folder.

Steps to protect the Stage folder:

 * Right-click on your Stage folder and select Properties
 * Go to the Security tab
 * Remove all the users that have permission
 * Add a new user via the "Add User, Group, or Built-in security principal" window. Call that User Everyone
 * Give this user new permissions for the folder by ticking the boxes as shown in the image below.
 * Apply and the result should look like the third picture on the image.

The Stage folder, subfolders, and files are now protected and can't be overwritten by accident. Please remember to save new custom levels in a separate folder.
