Bi fold doors usually have three post points: 2 on the side that isn't supposed to move (top and bottom of the part next to the wall) and 1 that does. The worst part that I had in my bifold doors was keeping that third post into the slide you have in that first picture. If I had it to do again, I'd put something else there: keep it an open concept closet, or put telescoping doors on it or something. Good luck and keep us posted?
