Type the "cd" command followed by the path of the file that you want to change the attributes for. For example, to change to a folder called "C:Documents," type "cd C:Documents." Type "attrib (file name)" and press "Enter" to see the file's current attributes.
A hidden file is any file with the hidden attribute turned on. Just as you'd expect, a file or folder with this attribute toggled on is invisible while browsing through folders — you can't see any of them without explicitly allowing all of them to be seen. These are often important operating system-related files.
icacls is a command-line utility that can be used to modify NTFS file system permissions in Windows Server 2003 SP2, Windows Server 2008, Windows Vista and Windows 7. It builds on the functionality of similar previous utilities, including cacls, Xcacls.exe, Cacls.exe, and Xcacls. vbs.
File attributes are metadata associated with computer files that define file system behavior.
