Core is synchronizing.
This means the whole blockchain is being donwloaded and verified.
Afterwards you'll be able to see the balance of your wallet.
However, if core already synced past the date you didn't transact anymore (e.g. already synced to 2016 already, but you didn't use core since 2014), the shown balance is the final balance of your wallet.
And before working on your wallet file, please create several copies and preferably store them on different drives.
