Q: In the properties of the folder, it is found that the “read-only' property has been checked by default, but it is grayed out and cannot be removed. Why is this?
A: Actually the file The folder does not have the "read-only" attribute, which is grayed out because in some cases the system does not allow the "read-only" attribute of the changed folder. If we need to change the folder's "read-only" attribute, for example, to add the "read-only" attribute to the J:\\HelpOnline folder, you can run the “attrib J:\\HelpOnline +r” command. Running “attrib J:\\HelpOnline -r” removes the “read-only” attribute.
