- I can only answer for Stacker, since that's all I have.

- I have not noticed any reduction in performance on my 20 MHz 386.

-
- Works very well. Compression is about 2:1 for most Windows files.
-
- > 3) Are there compatibiliy problems with memory managers?
-
- I was unable to get Stacker to use EMS generated by EMM386 or QEMM, so I
- do not use that option. It will run properly without using EMS.

- It depends on the data, but 2:1 is about what you get if you don't try
- to compress any data (using ZIP or GIF or LZH or whatever scheme).

-
- This is not true. Stacker will stack an existing drive with its data,
- through the INSTALL program. I did this and it works. It is, of
- course, advisable to back up everything first, in case a power failure
- interrupts the process. It takes quite some time, depending on how much
- data you have.
-

- Stacker takes about 40K.
-

-
- Yes.

-
- Stacker does a good job of trying to recover when its files are damaged.
- However, a bad write to the wrong place can render everything unreadable,
- but DOS has this problem, too. I've had data destroyed while using
- Stacker, and I've had data destroyed while NOT using Stacker. That's
- the way MS-DOS is.
-
- In short, Stacker is no better or worse than DOS as to performance or
- resistance to errors. It takes 40K for the driver, and it gives you
- twice the hard disk space in most cases. If you load the driver high,
- you'll never notice it, most likely.
