title: File Transfers
description: Transferring files to and from your serverlet over SFTP.
---

Uploading and downloading files to a serverlet is done via SFTP (Secure File Transfer Protocol), which runs over SSH. This file transfer is always encrypted and secure. FTP and FTPS aren't supported.

Every serverlet has its own SSH server that handles transfers, so transfer speed is partly affected by the serverlet's performance. The SSH port number can be found in [Administration](https://old-app.futrou.com) under the serverlet's Overview tab.

## How to do it

You can use clients like FileZilla or WinSCP to transfer files. Transferring via the `scp` command is also possible. Here's the process using [FileZilla](https://filezilla-project.org/download.php?type=client):

1. Download, install, and launch FileZilla
2. The serverlet must be running
3. The password must be set in [Administration](https://old-app.futrou.com)
4. Host: `sftp://{physical server address}` (e.g. `sftp://serlo.futrou.com`)
5. Username from the list in [Administration](https://old-app.futrou.com)
6. The user's password
7. SSH port (e.g. 10022) from [Administration](https://old-app.futrou.com)
8. Connect by clicking Quickconnect

If everything went well, you should see the serverlet's folders on the right side of the client. Your folder is `/srv/` — see [Directory Structure](/docs/serverlet/structure/).
