i have a really old btyecoin wallet i found i need advice on using it

[sorr]

hi i found an old bytecoin wallet an a wallet.dat from 2013 . it's possible theres nothing in there . i need to know obviously , i had a bit back then . The new wallets don't seem to work with wallet.dat , an i tried alot of the older wallets . possible im not doing it correctly perhaps . Also how many kilobytes would the wallet.dat have to be to have something worthwhile in it ? thanks to anyone who helps .
