System properties
The system properties of the file refer to the system file, which will be hidden. Under normal circumstances, system files cannot be viewed or deleted. It is a protective attribute of the operating system for important files to prevent these files from being accidentally damaged.
Hidden attributes
When viewing the name of a disk file, the system generally does not display file names with hidden attributes. Generally, files with hidden attributes cannot be deleted, copied, or renamed.

For a file with read-only attribute, you can view its name, it can be applied and copied, but it cannot be modified and delete. If you set an executable file to be read-only, it will not affect its normal execution, but you can avoid accidental deletion and modification.
