BO Publication [ File system : Password Changed ]

  Hi,
 
    Adaptive Job server--->properties --->Destination--->FileSystem--->User name  Administrator --->Password ( Now updated )

  Now reports those are scheduled for publication to filesystem might be using Old password for Administrator.

  My problem is how can I update, the password for All reports those are using File system for Publication or I have to do it one by one?
  Please let me know if anybody has an idea.

Regards,
Tushar
