Importing Another Contract

Question

Trying to Import another file. SimpleStorage.sol in this case but keep getting the error message that says cannot find the file. SimpleStorage.sol is the name of the contract, it's on the tab right next to my current contract. How do I get the current contract to find SimpleStorage.sol?

//SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "./SimpleStorage.sol";

contract StorageFactory {

SimpleStorage public simpleStorage;

function CreateSimpleStorageContract() public {
    simpleStorage = new SimpleStorage();
} 

}
