There are two path rules, one by Brummfondel on the DLS and the other by _mutton_ which is built in. They both work fine in TS12. I put information on these rules in this thread
There is also a further link in that thread to another thread of mine which gives some information about how to set the rules up.
If you want to see an example of the _mutton_ rule being used I have a session on the DLS for the built in ECML route which uses mainly built in content. There are just some driver commands and rules to download. It's the only one I have on the DLS so just search for my username.
