PLEASE CAN YOU KINDLY EXPLAIN STEP BY STEP PROCESS FOR YOUR FOLLOWING REPLY AS I AM NOT FAMILIAR TO HOW TO DO THE FOLLOWING:
You have to use multibit to open the file. From there you can export the keys and import them into core (meh) or just create a transaction from your old wallet to your new one (safer and easier).
Any additional comments or advise is & will be much appreciated.
