@Rob – thank you for sharing this.
It's working very well!
One question about the numbering of files:
Why would be number "10" be expressed as "010" ?
(Don't get me wrong, I'm just curious, I see no real problem in that.)
Example file names after running a test on a document named: "1-100-CS5.5.indd" with 100 pages, one section, section starting at page named "1", section ending at page named "100".
