Attributes allow the search to filter files and folders based on their attributes.
Attribute drop downs can be one of three values: On, Off, or not applicable. Setting the value to On means the attribute must be set on the file or folder, where as setting the value to Off means the attribute must not be set. Setting the value to '--' means the value of attribute will not be checked.
The 'Use Attributes' check box quickly switches on or off attribute searching and the 'Clear All' button sets all attribute drop downs to 'Either'.
