What is the Realtek PCIe CardReader Windows Driver?

The Realtek PCIe CardReader is a device driver that enables your Windows computer to interface with a Realtek-based PCIe (Peripheral Component Interconnect Express) card reader, which is commonly used to read and write data from memory cards such as SD, MicroSD, and MMC cards. The driver ensures that the operating system can properly recognize and communicate with the card reader, allowing you to transfer files between the memory card and your computer.
