Files.com's SFTP server supports the SCP protocol, another file transfer protocol that is built on top of SSH.

While there are technical differences between SCP and SFTP - SCP cannot delete or rename items, for example - transferring files using either protocol will work the same.

SCP is commonly used "under the hood", often for transfers between servers. As a result, if your connection was configured by someone else, such as your IT department, you might not realize you are using SCP rather than SFTP because the end behavior will be identical. Modern SCP programs may actually use the SFTP protocol by default.

Using SCP with your Files.com site will work exactly the same as SFTP, even using the same ports. All of the available SFTP settings for your site, including ciphers and SSH Key authentication, will work exactly the same, whether you connect with SCP or SFTP. Any actions performed through SCP will appear in your logs as SFTP activity.
