hello, 

i want to know if it possible to delete answers (not manually), because i have 260 000 answers...and my backup is so heavy..

(my website is free and members like to do quiz)

i want to know 

1 - i see it is possible to delete 500 answer so i can do it manually

2- is it possible to delete after 3 years or 2 years (or a certain time)

3-i can go to myphpadmin and insert line (is it possible to have line to delete answers since 2 years ?)

excuse for my explanation (i am not an english native speaker)

best regards
