Add Files fails when file name contains " character

[duongdominhchau]

Specifically, if the file name contains one ", nothing will happen when clicking OK button. If it contains two ", it will discard the part not inside " pair and throw out a Cannot open file error. Similarly for more than two ", but the error message is a little different: the first quoted part will be kept and everything else will be discard, including the remaining quote characters (i.e: a"b"c" becomes b).

There is also a similar bug with the # character.
