| About attrib Attrib allows a user to change the properties of a specified file. Using attrib, the user has the capability of changing the file to have any of the below attributes. Note if you're wanting to change the ACL's of a file see the CACLS command. Read-only - allowing the file to be only viewed and not written to. Archived - allowing Microsoft backup and other backup programs to know what files to backup. Hidden - making the file invisible to standard users. System - making the file an important system file. |

Typing attrib by itself will display all files in the current directory and each of their attributes. If any file is hidden it will also display those files.
attrib +r autoexec.bat
Add the read-only attribute to the autoexec.bat file so it cannot be modified until the read only attribute is taken off. This is helpful for important system files or any other file that you do not want to have mistakenly edited or changed by another program.
attrib +h config.sys
Add the hidden attribute to the config.sys file causing it to be not be seen by the average user.
attrib -h config.sys
This command will do the opposite of the above command. Instead of hiding the file it will unhide the file if hidden.
- Additional examples and information about displaying hidden files in MS-DOS can be found on document CH001039.
