yes, you can insert a FAT32-formatted flash drive into the USB port. You may need to download a utility to format a large capacity drive as Windows doesn't normally allow it, or you can have the TV do it. Using the TV the drive can be formatted as a removable drive, allowing you to plug it into a PC and copy media for display on the TV, or it can be formatted as extra storage for the TV, which lets you install apps on it but rendering it non-removable.
