Hidden files

One or more files that exist on a computer but don't appear when listing the files. For example, in MS-DOS, when doing the dir command without any additional switches, you cannot see hidden files. However, using the "attrib" or "dir /ah" command enables you to view any hidden files in the current directory.

Note: It is important to realize that files can also be hidden using a software program or other commands. In order to view these files you need access to the program or a password to have the program unlock the files so they can be viewed. Files may also have rights set to them that allow or prevent users from viewing the files. In order to view these files you must be given the appropriate rights by the administrator or super user.
