BE 2012 - How to change or view the backup method for incremental

Hello,

Sorry for my bad english.

I'm using the french of backup exec 2012 SP4 and i'm using complete backup the sunday and incremental backup each other day of the week.

I'm unable to see the "Files and folders" in my job but i can see it inthe defaut parameters of a job or when i'm creating a new job. Can we see the "Files and folders" section of an existant job ? I don't know which parameters is used for the incremental (Time modification or Archive bit). I searched in the database but it's not very easy...

Thanks for the response
