  1. I’d like to see a software to make it automatically, to apply to a bigger amount of files, and to apply selective permission easily (only write, only read, only execute, etc…), and restoring the default permissions if something goes wrong.

    Is there a method to make the user or the machine that try to change the folder not aware that the folders are locked? Like for instance an automatic software update (I want to update without errors, and prevent some files inside the tree to be changed), or window automatic update to be fooled thinking it updated the system with success?
