The SWAPPATH command points to the directory and determines the size of the swapper.dat file. The swapper.dat file stores currently unused blocks of RAM. This is done to increase your available memory.

note: To enable swapping the MEMMAN command must be set to SWAP.

SWAPPATH=Path MinFree InitSize

Default settings:

• SWAPPATH=C:\OS2\SYSTEM 2048 2048

Parameters:

• Path

  Path can be any path to the swapper.dat file .
  Default = C:\OS2\SYSTEM
  

• MinFree

  The Minfree parameter defines the minimum available free space that the swapper.dat file can grow to before it stops consuming disk space. If you set it, for example, to 1024 the swapper.dat file can grow until the free space remaining is 1024 Kbytes.
  Minfree can be in the range from 512 to 32767
  Minfree is expressed in Kbytes.
  

• InitSize

  The InitSize parameter sets the starting size of the swapper.dat file. The file can grow but the file will never be smaller than the initsize. To find out a good value for initsize, start some big applications and work with them. From time to time, check the size of the swapper.dat file. Take the biggest value you see and add 10% to determine the initsize parameter.
  InitSize is expressed in Kbytes.

See the examples below.

If you would like your swapper.dat file to be in the C:\Swap directory, start with a size of 40 megabytes and stop growing at a free space of 2 megabytes, enter this line in your config.sys file:
