Re: Sequential files

Since I got no replies, I guess this is how it is to be done.
I changed my mind about counter=0 and I'm using counter=1 now.

I was wondering if I could zero pad the files?
If there are less than 9 files then I wouldn't change anything, but
when I reach example_10.png, I would rename the first 9 files to
example_01.png, example 02.png and so forth.
And I would do the same thing with hundred and thousand.
example_001.png and example_0001.png
