Use folder rules to manage your library content automatically. There are two ways to
define rules: create your own rules or link to rules already created for a different
folder.
When you define a rule, it only applies to new content added to the folder. Items that
were in the folder before the rule was defined aren't affected by it. You can manually apply
the folder rules with the Run Rules action.
Note: Even though the folder
doesn't have its own rules, it could have inherited rules from a parent folder. A message on
the Rules page lets you know if this is the case.
