What do you mean by attributes of a DOS file?
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.
