Thank you for your reply and have been experimenting with this a little. Performance gain (or loss) is minor. Am still working on a built-in timer, but the differential is mere seconds (if any) on a total body of about 200 files and combined requiring 40MB.

And the dot (.) is the part of the file name: w+ being the standard file name and d{6} being the 24hr time of the time of download. So a file would have a name such as: scores.234506.csv
