Boon in areas with little space for using other solutions...
for example- like a pocket door, a barn-style slider can work great in areas where you can't swing a standard door or a bifold would still stick out too far when open (like in a narrow hallway or similar alcove)...and in places like that where some existing in-wall items like pipes or wiring make a standard pocket frame installation cost prohibitive or impossible, as long as you have enough flat wall space next to it for the door to operate in, you can still have the benefit of a completely unobstructed opening with the door open
