I would like to point out that the assigned drive letter does not necessarily need to be "Z" for the mentioned copy operations, does it?
No, it does not. Any drive letter will do.
The required files can also optionally be provided from a network location (by the universal/uniform naming convention).
Yes, although Wine has no native support for UNC paths, they must be supported by the underlying system, and configured within Wine: http://www.winehq.org/docs/wineusr-guide/misc-things-to-configure#AEN414
