lines 648, 653: there are some unmatched quotes and some typos:
 message = 'There is one duplicate ' +
+ '["+files[duplicates[0]].name+"].' +
+ '\\n Press ok to replace it' +
+ 'otherwise ancel to ignore it.';

should be:

 message = 'There is one duplicate ' +
+ '['+files[duplicates[0]].name+'].' +
+ '\\n Press ok to replace it ' +
+ 'otherwise cancel to ignore it.';

(this has been fixed on production)
