Bi-fold doors consist of two panels that fold against each other when the door is open. They pivot on side hinges while the top of the door runs along a track to keep it in place. They are often installed in laundry rooms, pantries and other areas where a traditional closet door takes up too much space when open. If you've decided to remove a bifold door, you can do so with almost no tools.
Open the bifold door so that it's flush against the side of the door frame and the panels are folded against each other. Grasp the door and lift it upward. One you feel the door rise, pull the bottom of the door away from the closet to dislodge it. Lower the door by 1 to 2 inches and pull the top of it out of the track. Set the door aside.
Look at the top of the door frame for a metal track. Locate one of the screws in the centre of the track and remove it with a screwdriver. Repeat the process to remove all remaining screws on the top of the track. Pull the track free from the top of the door jamb.
Look at the floor near the side of the door jam to locate a metal bracket, called a jam bracket. Locate the two screws that secure it to the jamb and the one screw that secures it to the floor. Remove all of the screws with a screwdriver. Pull the bracket up off of the floor.
