- I am used to unix, so I thought of the same thing. I started to think
- about how to do it before I remembered that MSDOS doesn't have pipes.
- It emulates pipes by using temporary files, so you would have
- temporary files as large as your backup set. So it might work if your
- backup set was no larger than about 1/3 of your RAM disk; in other
- words it would not be very practical. You would also likely run into
- the 640K memory limitation, so you could probably only work with about
- 200K of files.
