According to what you wrote, it should be working just fine. What are you getting instead?

And when you want to save as 01, 02, 02.5, 03 do you mean as a subfolder of series? If so, you just need to add /{series_index}/ to your template.

Also, your current template has a problem that makes it not work properly if there is no series. Do you see the

:|{stuff1}|{stuff2}

in your template? This allows you to only add {stuff1} before the series_index and {stuff2} after, IF series_index exists.
See http://manual.calibre-ebook.com/temp...ced-formatting for a more in-depth explanation.

Your current template should therefore look like this:

{author_sort:.1}/{author}/{series:||/}{title}{series:| - |}{series_index:0>2s| -|- }{author}

not like this

{author_sort:.1}/{author}/{series}/{title} - {series}{series_index:0>2s| -|- }{author}

I have moved the "/" which separates folders from after the series to the conditional after-the-series-if-series-exists, and same goes for the " - " right before the second {series}.

if you wish to switch from "A (1st letter of Authors last name) > Author (First Last) > Series (if applicable) > Title - Series -03- Author" to "A (1st letter of Authors last name) > Author (First Last) > Series (if applicable) > Series Number (if applicable) > Title - Series -03- Author" then use this instead (addition in red)

{author_sort:.1}/{author}/{series:||/}{series_index:0>2s||/}{title}{series:| - |}{series_index:0>2s| -|- }{author}
