attrib

Displays, sets, or removes attributes assigned to files or directories. If used without parameters, attrib displays attributes of all files in the current directory.

Syntax

attrib [{+|-}r] [{+|-}a] [{+|-}s] [{+|-}h] [{+|-}i] [<drive>:][<path>][<filename>] [/s [/d] [/l]]

Parameters

Parameter Description
{+|-}r Sets (+) or clears (-) the Read-only file attribute.
{+\|-}a Sets (+) or clears (-) the Archive file attribute. This attribute set marks files that have changed since the last time they were backed up. Note that the xcopy command uses archive attributes.
{+\|-}s Sets (+) or clears (-) the System file attribute. If a file uses this attribute set, you must clear the attribute before you can change any other attributes for the file.
{+\|-}h Sets (+) or clears (-) the Hidden file attribute. If a file uses this attribute set, you must clear the attribute before you can change any other attributes for the file.
{+\|-}i Sets (+) or clears (-) the Not Content Indexed file attribute.
[<drive>:][<path>][<filename>] Specifies the location and name of the directory, file, or group of files for which you want to display or change attributes.

You can use the ? and * wildcard characters in the filename parameter to display or change the attributes for a group of files.

/s Applies attrib and any command-line options to matching files in the current directory and all of its subdirectories.
/d Applies attrib and any command-line options to directories.
/l Applies attrib and any command-line options to the Symbolic Link, rather than the target of the Symbolic Link.
/? Displays help at the command prompt.
