Couldn't figure out where data folder was to extract to on my win10 so didn't use. Wallet ended up syncing over 3-4 days downloading bc and just transferred coins over. Nice and quick too... 20sec
Still cant figure out ixc wallet, always on 0 connections, so made Coinomi IOS wallet and transferred there.
To find executables/Data files try search %appdata% > roaming > i0coin
For the IXC wallet you can temporarily remove the wallet.dat by sliding it out of the executables onto your desktop or whatever after creating a backup and see if fresh .dat helps it sync.Once it syncs remove the generated one and reinsert back in the original.
