Goals from Jack Hamilton, Sam Stanton and Lewis Vaughan saw Rovers inflict a third defeat on their Fife rivals this season, while the Pars' Lewis McCann also saw a penalty saved by Kevin Dabrowski on a dominant side for the Kirkcaldy outfit.
Jeanfield Swifts had been the story of the Third Round as they defeated Elgin City 6-0 but there was to be no repeat as Clyde defeated them 2-0 in the other Friday night match.
The other 18 ties would take place on a busy Saturday of Scottish Cup action.
Championship leaders Dundee United were the highest ranked side in the competition but - despite a Kai Fotheringham double - the Tangerines were defeated on penalties by League One side Queen of the South after a 2-2 draw in regulation time.
The day's other major shock came at Ainslie Park as League Two Spartans defeated Championship side Arbroath 2-1, with Jamie Dishington scoring the winner early in the second half.
Alloa Athletic avoided a shock against Dunbar United, who had defeated East Fife in Round Three. Despite falling behind to an early Michael Barfoot strike, Alloa hit back with goals from Kevin Cawley and Conor Sammon as they secured a hard-fought 2-1 win.
Another side to avoid a shock were Ayr United, who trailed 1-0 to a Kieran Shanks goal, before Sean McGinty equalised deep into added time. The Honest Men then triumphed in extra time as Fraser Bryden secured their safe passage into the Fourth Round.
Dumbarton also prevailed into extra-time, winning 5-4 away to Annan Athletic in the game of the day.
Partick Thistle were comfortable winners over Queen's Park in the day's all-Championship match-up, while last year's semi-finalists Falkirk defeated Formartine United 3-0 to also progress to Round Four.
Inverness Caledonian Thistle - the side who defeated Falkirk in last season's semi-final - were also in action as they eventually overcame a stubborn Cowdenbeath, to prevail 2-0.
