How do I restore a backup?
Are you looking for the roaming folder? you can type
%appdata% in the search tab of your computer and it will redirect you to roaming folder. Find ICOBID folder and open it. You will see the wallet.dat and other files there. Back up wallet.dat (if you are resyncing) delete all files in the folder except wallet.dat.
