Hi Rusty Cauthen,
If you want to transfer the folder directly between the PC and iPhone, another option is to connect the iPhone to the PC with a USB cable and use Apple Devices for Windows for supported file transfers.
You can install Apple Devices from the Microsoft Store, connect and unlock your iPhone, then select the device and check the available file-sharing options.
Please note that file sharing depends on the apps installed on the iPhone, so an entire Windows folder may not be transferable as-is.
I hope this gives you another practical option.
