Norton Desktop for Windows (EP.EXE)
-----------------------------------
If the data-recovery program Erase Protect (EP.EXE) is loaded
from the AUTOEXEC.BAT file, you need to disable it when setting
up Windows 3.1, especially if you are upgrading over a previous
version of Windows. Erase Protect tries to save copies of all
deleted files, which can cause you to run out of disk space
while running Setup.

It is recommended that you run Erase Protect with a permanent
swap file, not a temporary swap file. If you are using a
temporary swap file, you need to exclude files with a .TMP
or .SWP extension from erase protection.
