How to delete older default address folder (list)

Hi everybody, i've read bitcomet post rules and i do believe it will be not necessary to describe all itens (antivir, internet connection and so on) related to my issue (minor doubt).
I am using bitcomet 1.36 (64bit version) and I don't know how to erase old entries (folder address list) into the panel to choose the folder i will want to send my download.

Thank you and Happy Christmas and New Year !!!
