SFTP stands for Secure File Transfer Protocol. It lets you securely upload, download, and manage files on a remote server.
You usually need:

Download and install FileZilla Client.
At the top of the window, fill in:

| Field | Example |
|---|---|
| Host | sftp://sftp.example.com |
| Username | your_username |
| Password | your_password |
| Port | 22 |
Make sure the host starts with:
sftp://
Example:
sftp://files.seven-labs.com
Click Quickconnect.
The first time you connect, FileZilla may ask you to trust the server’s host key.
Click OK only if you trust the server.
After logging in:

To upload a file, drag it from the left side to the right side.
To download a file, drag it from the right side to the left side.
Download and install WinSCP.
Open WinSCP and enter:

| Setting | Value |
|---|---|
| File protocol | SFTP |
| Host name | sftp.example.com |
| Port number | 22 |
| User name | your_username |
| Password | your_password |
Click Login.
If prompted about the server key, confirm it only if you trust the server.

Drag and drop files to upload or download.
Most modern systems include the sftp command.
Use this command:
sftp username@sftp.example.com
Example:
sftp sam@files.seven-labs.com
If the server uses a custom port:
sftp -P 2222 username@sftp.example.com
Example:
sftp -P 2222 sam@files.seven-labs.com
Enter your password when prompted.
Once logged in, you can use these commands:
| Command | Description | Example |
|---|---|---|
ls | Lists files on the server. | ls |
pwd | Shows your current folder on the server. | pwd |
cd | Changes folders on the server. | cd uploads |
put filename.txt | Uploads a file to the server. | put document.txt |
get filename.txt | Downloads a file from the server. | get backup.zip |
mkdir | Creates a folder on the server. | mkdir newfolder |
rm | Deletes a file from the server. | rm oldfile.txt |
exit | Disconnects from the SFTP server. | exit |
sftp myuser@sftp.example.com
Then upload a file:
put report.pdf
Then disconnect:
exit
Check that your username and password are correct.
The server may be offline, the address may be wrong, or a firewall may be blocking the connection.
SFTP usually uses port 22, but some servers use a custom port like 2222.
Your account may not have write permissions to that folder. Try uploading to your home directory or contact the server administrator.
