How to use

Connect the card reader to a compatible host using a USB Type-C cable or a directly connected Type-C port. Insert a CFexpress Type B card into the slot with the contacts aligned according to the device marking. The host should recognize the card as an external drive; then copy or move files using the operating system's file manager or media management software. Remove the card or disconnect the reader only after unmounting or ejecting the drive from the host to avoid data corruption.

For sustained performance, use high-quality CFexpress Type B cards rated for the required write and read speeds. Ensure the host device supports USB Type-C at the specified speeds for optimal transfer rates. Avoid exposing the reader and media to extreme temperatures, moisture, or physical impact during transport and use.
