Re^3: Unique filenames with Time::HiRes

Use the creation date of the files to order them.

Since he can create several files in a short interval, so that even Time::HiRes isn't updated quickly enough (update interval is 18 times a second, on Windows), and the resolution of creation date is in general only 1 or 2 seconds, I am certain you haven't solved the OP's problem.

The exact running order is going to be dependent on a lot of factors outside the OPs control. Depending on the exact requirements having unique filenames and a rough order may well be enough.
