Bug ID: 54903
           Summary: PeaZip can't open Z: drive
           Product: Wine
           Version: 5.5
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]

Terminal output

When PeaZip starts, it displays a file explorer. Browsing files on the C drive
works fine, but if you double-click Z: or a directory symlinked to a directory
on drive Z, the program freezes. Then, if you click in the file explorer again,
an error dialog appears that says "Index Out of range".

This was a regression in Wine 5.5. `git bisect` says:

--- Comment #1 from Zeb Figura  ---
It's probably FSCTL_GET_REPARSE_POINT, yes, although even before 6b498d98 I
expect it would have had that same behaviour on a symlinked directory.

However, it does turn out that it's incorrect to report a drive root as a
reparse point. This is easy to fix for NtQueryAttributesFile(), but harder for
NtQueryInformationFile() since we don't have the original NT path for the
latter.
