These sound files overwrite the originals so
make sure to backup the original files before installing
by either moving them to a seprate folder or renaming them

Replaces the following files:
WalkLmd
WalkRmd

I recommened using a media player of your choice to listen to the sound effects
before installing

This is also OpenMW friendly, 
and if you are using OpenMW the installation is the same.

[Installation]
Place Data Files folder contents inside: 
C:\Programfiles\Steam\steamapps\common\Morrowind\Data Files

[Uninstall]
Provided that you backed up the original files, 
just delete the modded ones and rename them back, 
or alternatively,drag and drop the original files 
into the sound\fx\foot folder
