Hello Ovanes,

Thanks for your reply.

You means like this?

       catch ( const fs::basic_filesystem_error<fs::path>& e )
       {
               // transform e.what() to a new string by search and replace
               // rethrow an exception
       }

That would be ok for this single case. But who knows if there's other
similar cases that need this similar hand-written code processing?
I want to depress the similar message in a uniform way.
