I try to open the C drive in Wine environment ether form manual or terminal, and every time VLC player will open and try to run all file in c drive as media file. It will showed all of them in the playlist . It will also gave a error report as in the following: "No suitable decoder module VLC does not support the audio or video format "undf". Unfortunately there is no way for you to fix this."
I did uninstalled both program and reinstall them, but with no improvement!
In Nautilus, the file manager, right-click on the folder, select 'Open with another application', choose Nautilus, check 'Remember this application', and the folder should open with Nautilus afterwards.
Your "c: drive" in wine will be in /home/user/.wine/drive_c, where user is your username. To find it in Nautilus, you have to press Ctrl-H, to view hidden files. Any Linux file or folder with a '.' as the first character is hidden by default.
