I also use the Thunar file manager and I have to admit that I always found it annoying that Wine puts the virtual C drive inside a hidden folder. It makes it cumbersome to navigate.
One way of solving this is to find the virtual C Wine drive and then move all the files and directories inside it to another location. After that, you can use the "winecfg" program to change the location in the Wine configuration files. That saves you having to use the "show hidden files" option all the time.
An even easier option is to access the View menu in Thunar and change the Location Selector to Toolbar style. From there, you can press the Home button on the toolbar, and then type "/.wine" at the end of the path text box. If you are reasonable good with the keyboard, that gets you moving much more quickly than having to navigate through dozens of hidden folders
Hope this helps.
