DS_Store files are automatically created by Mac OS X Finder in browsed directories. These files contain information about system configuration. If you upload them along with other files, the files can be misused to obtain information about your computer. For more information, see Apple security updates.

  2. Enter the following UNIX command:

    sudo find / -name ".DS_Store" -depth -exec rm {} \;
