How do you delete data from a Nintendo 64 memory card?

In order to erase previously saved data on a memory card for the Nintendo 64, you have to hold the start button while you turn on the N64 game system with the game cartridge in it. It should direct you to the Memory Card Manager. From there you can see all the game saves and data stored on the card. All you have to do now is select the games/data files you want to delete.
