Hi,
What if we map the unixfs extension on the desktop instead of on mycomputer? So if HKCR\Software\Microsoft\Windows\Current Version\Explorer\Desktop\Namespace{UnixDosFolderCLSID} is present, the desktop folder would forward ParseDisplayName calls to UnixDosFolder instead of MyComputer.
We could de-activate the special case of enumerating all child's of MyComputer in the file dialogs iff unixfs is rooted at the desktop.
This way we wouldn't have to introduce a second "MyUnixComputer" and the user could expand MyComputer, if he forgot where there C: drive is mapped. But he would'nt see the drives until he does so.
Bye,
