Comment 4 for bug 403249

Theoretically a person could have 10 WINE instances (because of 'WINEPREFIX') and 10 Windows partitions at the same time, so the most basic preference would be a directory browser to choose the root (/mnt/windows/, ~/.wine/drive_c/, etc.).

As a hack you can put the WINE paths in CleanerML for yourself (like your example), but I don't want to ship hard-coded paths for everyone.
