Read Only

If you would like to protect a file from being accidentally edited, you can open it as a read only file. To do this, click File, Open to access the Open File dialog. Browse to the file that you want to open. Then use the drop down list on the Open button at the bottom of the dialog to select Open Read Only.

When you open a file for reading, you can scroll through the file, select and save blocks of text, and copy selected blocks to another file. You cannot add, delete, or move text in the displayed file. This option protects a file from being accidentally edited and also allows you, in a network environment, to view a file that is already open on another terminal.

You can use the re or read command on the action line to open a file for reading only. See read command.

You can also use the attrib (attribute) command to create a file that is for reading only. See attrib command.
