An estate folder is a folder that you can (and should) create to help your loved ones after your death. It's essentially a folder outlining your assets, debts, and bills, enabling your survivors to handle your estate much more quickly and easily. Specifically, this is to help them terminate all accounts in your name, pay any outstanding debts you have, and collect all of your assets so that your estate can be handled properly. Additionally, it's a useful tool to take stock of your circumstances in terms of budgeting and planning for the future.
