The phone and the Cardputer must be on the **same Wi-Fi network**.

1. On the Cardputer, open **Storage** and press <kbd>w</kbd>. You should see a QR code, an address and a six-digit code.
2. On the phone, **scan the QR code** with the camera and open the link. The page opens on the card's folders. (Without a camera: type the address in a browser, then the code.)
3. **To download:** tap a folder to go in, tap a file to download it.
4. **To upload:** go to the folder you want, tap **Upload files** and pick one or several. A bar shows the progress; if a file with that name is there already, the page asks before replacing it.
5. **New folder** and **Delete** do what they say. A folder must be empty to be deleted.
6. On the Cardputer, press Back. Sharing stops, and the code is no longer good.

## What to expect

- About **200 KB a second**: a 3 MB photo takes a quarter of a minute.
- **One thing at a time.** While a big file moves, the page waits.
- The device's screen shows how much has gone in and out, and the last thing that was asked.

## Good to know

- **It is not encrypted.** Use it on a network you trust, or [through the VPN](/guide/vpn/).
- Five wrong codes close it for a minute.
- It works from a computer's browser too.
