If you want it to be viable in court you need to have an eDiscovery firm do it. A text file of SMS/MMS means nothing. You should talk to a lawyer and see who/what they suggest. Could also possibly get a copy from your carrier, but that almost surely requires a court order (and a waiting period) too.
