Farrow, 28, wrote an open letter in the New York Times, accusing Allen of "sexually assaulting" her back in 1993.
Allegations of abuse began in 1993, but Allen, 77, has consistently denied any wrongdoing, and has maintained his innocence.
"What's your favorite Woody Allen movie? Before you answer, you should know: when I was seven years old, Woody Allen took me by the hand and led me into a dim, closet-like attic on the second floor of our house. He told me to lay on my stomach and play with my brother's electric train set. Then he sexually assaulted me.
Allen, 77, and Dylan's mother Mia Farrow, 68, began dating in 1980 and adopted Dylan and her brother Moses in 1987.
During a custody battle for the children in 1992, Farrow filed charges of molestation against Allen, but the case was later dropped.
"These things happened so often, so routinely, so skillfully hidden from a mother that would have protected me had she known, that I thought it was normal. I thought this was how fathers doted on their daughters. But what he did to me in the attic felt different. I couldn't keep the secret anymore," she added.
Allen is again niminated for Academy Awards this year for comedy-drama 'Blue Jasmine'.
