If you do not want to use the web interface to download and upload files, you can use the sFTP protocol in FileZilla, Linux command line or Windows Powershell.

sFTP Instructions

For FileZilla (Download):

• Protocol: SFTP
• Hostname: sftp.gcssemi.cloud (NOTE: .cloud NOT .com)
• Port: 2222 (important!)
• User: <your-username>

From Linux or Windows PowerShell:

sftp -P 2222 <your-username>@sftp.gcssemi.cloud
(that's a capital letter "-P")
