FreeDOS is an MS-DOS 6.00 clone, a 16bit operating system, so it will 
by itself only support 1MB (or 640KB as you mentioned), just as MS-DOS.
More than that can only be access by use of an XMS or EMS compatible 
memory manager. And due to all this, there simply is not a need for 
any swap file/partition (though some memory manager might create/use one)...
