Wait for file download and install on your pc, remember if you gonna hold a good amount of coins, backup your wallet.dat file in a usb. If you dont know how, let me know and i can post a thread about that.
Good luck.
There is no wallet.dat files for ARK wallets. Wallet.dat files are for coins that require blockchain syncs like btc/eth.
