See nabble

We should allow to configure fileExists=RenameAndRetry option, which allows you to rename the file and retry writing the file again, in case there already exists a file.

The trick is to find a optimal solution if you append a sequence number to a file. And when there is a lot of files. You kinda want to know what is the highest filename, (some way of listing and sorting).

Maybe a way to get a list of existing files based on a file name pattern, and a sort configuration. Then people can check in the list, to find a free sequence number to use etc.
