When mounted virtual Windows' C: drive from Mac finder, it is mounted as like '/Volumes/[C] Windows' on Mac's filesystem. By changing directory into the path on Terminal like: $ cd Volumes/[C] Windows/ and executes: $ ls -l It shows any file's permission as ''-rw-rw-rw-", and any folder's permission as "drwxrwxrwx". It seems they cannot be modified by "chmod" command. As a result, some tool chains fail to execute script files on Windows volume. How can I change the permissions?
