I have backuped my wallet and it created a file which is called atomic.dat. How do I use this backup file in order to restore my wallet? I tried drag and drop the file on the atomic wallet program but it said" url can not be parsed! this can be caused by an invalid Atomic address or malformed URI parameters" I have the wallet and it's running and it's ok now, but I want to have it as a backup in case my pc has some crash or anything. Also if I copy the entire wallet to another hardrive will it synch and have the same amount of coins if I open it again from there?
