I am doing a manual upgrade from 7.04 to 8.01 - and i compare files from the two directories to be sure i have copied them. I see a discrepancy with .fil and .hlp - they are now for instance, gwtsaen.fil instead of gwtsaus.fil. There are several of these.

Does this affect the language parameter in the mta or poa file - where I have "language-US".. Just wondering if that should be changed to "language-EN" now.

Maybe it has nothing to do with it - but was googling and saw reference to these files and the configuration file.

Thank you
