# Transfer files

Files go both ways in a session: you send files to the remote computer from the viewer, and a customer on Windows can send files to you. Your role needs file transfer for the session type (support or Access).

## Send files to the computer

1. In the viewer, select **Send file** and choose one or more files. Or drag files from your computer and drop them on the remote screen.
2. Watch progress in the transfer panel under the toolbar: name, size, progress, speed and time left.

Files are sent one at a time, in order. Select **Stop** on a row to cancel it. Each file is checked after it arrives, so a damaged transfer is never saved.

On the remote computer, files land in the **Blink** folder inside the user's **Downloads** folder. A file never overwrites one that is already there; a number is added to the name instead, for example `report (2).pdf`. The customer sees a **File received** notification.

On an Access device, files go to the Downloads folder of the user signed in at the computer's console. If nobody is signed in, the transfer is cancelled.

## Receive files from the customer

A customer on Windows sends you files with **Send file** on the banner, or **Send file to technician...** in the tray icon menu. While a file goes out, their banner shows its progress and a **Stop** button.

:::note
Sending files to the technician is not available on a Mac, from an Access device, or while Blink runs as administrator on Windows.

When a file arrives, nothing is saved until you decide:

1. The file appears in the transfer panel as **received · accept to save**.
2. Select **Accept** to save it to your browser's downloads, or **Decline** to throw it away.

If the file could run code on your computer (for example `.exe`, `.msi`, `.ps1`, `.bat`, scripts, shortcuts, disk images or Office files with macros), the panel warns you and the button reads **Save anyway**. Open such a file only if you expected it from that computer.

Your browser holds received files in memory until you accept or decline them: up to 4 files and 1 GB at a time. Accept or decline waiting files to make room for more.

## Limits

- You cannot browse the remote computer's folders from the viewer and pull files from them. To get a file from a customer on Windows, ask them to send it.
- Transfers stop if the session ends or the connection drops. Send the file again once you are reconnected.
