You might just want to refactor the error handler so that it calls a common function for displaying the error and pass in an indicator for the operation so we know which strings to use ( `Strings.ERROR_CREATING_FILE_TITLE` / `Strings.ERROR_CREATING_FILE` for the create case and `Strings.ERROR_RENAMING_FILE_TITLE` / `Strings.ERROR_RENAMING_FILE` for the rename case. )  but 
We should have similar messaging for both rename/create cases.  

I wonder do you think it's useful to show the OS error string for the rename but not the create case?  We might want to make the error more robust for create if you want to merge in the code that for showing the OS error information for create as well.
