These doors are often found in the kitchen and can be secured with a wooden dowel in the lower track.
You can also slide the door open and place screws in the upper part of the track leaving enough space so that when you close the door it misses the head of the screws. This prevents the door from being lifted up and out.
If you need to remove the door, simply open the door and remove screws.
