I recently got the floor done in the bathroom replacing vinyl with tile. Since then the closet door that would fit earlier no longer fits. I didn't pay much attention to it until now. We've moved to a different house and plan on renting and I imagine that the tenant would not like to have everything in plain sight. It appears that when the tile was put in, it raised the floor and a standard bifold no longer fits.

What are some of the quick and easy options to solve this issue? I've attached the picture of the closet
