>Logging the error is normally done with writing to a log file with strtofile. We have a special WriteToLog method which uses strtofile to write to the log file. You will need to implement your own logging of the error.

Thanks, It worked fine than before, Previously it was giving error at Many instances but now giving errors at 4-5 Instances when I take the sample of 1000 files, Seems that the Second TRY is making the conversion success. Is it not possible to Keep TRYING unless it succeeds using DO WHILE.
