Well I found a simpler way to do any nth file, using a similar method as the one I described above.
Imagine we want to select every 7th file. We set the numbering to start at 3 (10-7 = 3), with pad at 2 and breaking at 1. That way the first file prefix will be 03, second 04... Seventh will be 09, and the eighth would be 10, but since the first char changes, it breaks and it's renamed to 03. So all files beginning with 09 will be the seventh file.
With the 15th file? Numbering starts at 85 (100-85 = 15), pad will be 3 this time, and breaking again at 1. First file will start with 085, second with 086... The fifteenth will be 099, and the sixteenth would be 100, but again the first char changes, it breaks and will have prefix of 085. In this case, the files beginning with 099 will be the 15th file.
As I said, it's a matter of imagination. BRU is a very powerful and flexible tool. Understanding what each criteria does will unleash all the possibilities.
