The present invention provides a door system for a temporary, movable structure having a plurality of spaced apart frame members and a membrane stretched between adjacent frame members. The door system has multiple modules movable between open and closed positions. Each module has its own membrane, separate from the membranes of the structure, which is stretched taught over the surface of the module. In the open position, the modules do not obstruct the opening in the structure, and the membranes of the modules and the structure do not go slack. The membranes of both the structure and the modules are always under tension, thus being less susceptible to damage.
