text string extraction question

[Sean Sebastian]

How do I extract characters 6-10 (i.e., the 5 characters starting at the 6th position from the beginning) and append them to a file name?

With a match pattern, you could create a pattern which matches 5 character, then have a custom attribute which matches, and captures, the next 5 characters. You can then use that custom attribute in the Rename action.
