All files, DOS, or Windows have attributes. Files can be Hidden, System, Read-Only, Archive, or any combination of them. For example, there are some important windows files that are hidden, read-only, and system. On a windows operating system, you can right-click the file, and choose properties from the menu. At the bottom, you should see the attributies of a file. In DOS ( only because you brought it up ) you would need to be in the directory of the the file and type "ATTRIB [filename]" to view the attributes. Type "ATTRIB /?" to read how to change the attributes.
