This technique can be used to rename virtually any type of file, unless the file has been restricted or banned from being accessed in some way. It is possible to restrict access to specific files and folders on a Mac or MacBook if you are the administrator and you do not want other users to be able to modify or delete information stored in those files or folders. This will help to protect the identity of the folders and prevent unnecessary mischief.
There are also many third party tools that allow you to perform this trivial operation and some people fall prey to them. Please note that renaming a file is a built in feature and you do not need any sort of assistant software or tools to get this done. Any vendor marketing such a tool is clearly baiting you into a scam.
