bifold
nounCarpentry
A door, window, shutter, or divider consisting of two equal panels hinged together so that it opens by folding the panels against each other.
Why this one
The word describes the motion rather than the object, which is why it applies to doors, windows and shutters alike.
In use
Closet's only 30 inches, so hang a bifold on it; a swing door would block half the hallway.
