Remote file access from Android can be extremely useful when you need to fix a website, check a server or move files while away from a computer. The key decision is choosing the right protocol and verifying where you are connecting.
1. Choose FTP or SFTP
Use SFTP when your server supports it. SFTP runs over SSH and encrypts the connection. Traditional FTP does not provide the same protection unless an encrypted variant is configured.
2. Gather your connection details
You normally need a hostname or IP address, username, password or key, port number and the protocol your server expects.
3. Verify the server identity
For SFTP, pay attention to SSH host fingerprints. Verification helps you avoid connecting to the wrong server or an unexpected intermediary.
4. Transfer carefully
When replacing website files, server configs or backups, download a copy first. Upload to the correct remote folder and avoid overwriting files you cannot restore.
Common mistakes to avoid
- Using plain FTP when the server supports SFTP
- Ignoring SSH fingerprint warnings
- Uploading over an important remote file without downloading a backup first
- Connecting to the wrong folder or host
Common questions
Is SFTP the same as FTP?
No. SFTP is the SSH File Transfer Protocol and operates over SSH. FTP is a different protocol.
What port does SFTP usually use?
SFTP commonly uses port 22, although server administrators can configure another port.
Can I manage website files from Android?
Yes, if your hosting provider gives you FTP or SFTP access and your Android client can connect to the server.
