Wine directory structure used in Red Hat Linux:
===============================================

/usr/share/wine-c is the root directory (aka C: drive) wine looks for
by default. It contains (empty) C:\windows and C:\windows\system
directories, needed to operate Wine without an existing Windows installation.

If you want to use Wine with an existing Windows installation that is mounted,
for example, in /mnt/windows-c, edit /etc/wine.conf to say

[Drive C]
Path=/mnt/windows-c
Type=hd
Label=Whatever
Filesystem=win95

instead of the defaults set by installation.

If you do this, you can safely remove /usr/share/wine-c.
(Alternatively, just mount your Windows partition to /usr/share/wine-c.)
