A ram disk is a part of the memory used as a hard disk drive, ie with fopen,
fwrite, ....

This implies the use of a dedicated driver.

Pro : very fast compared to an actual disk drive, as the ramdisk driver use
memory access

Cons : the data are stored in volatile memory : you may lost them if you
do not backup the files on an actual hard disk.

This was very useful  when there was not DJGPP as it was a way to temporary
store quickly data from programs which cannot store them in 640K.

Today, I think that using a ramdisk which DJGPP is not a good idea because
the consumed memory is lost for DJGPP : the program will swap more frequently.
Am I right on this last point ?
