Copy Filenames / As URL shows FTP and not SFTP

When I run "Edit / Copy Filenames / As URL" from a SFTP login DO returns the protocol FTP and not SFTP:

ftp://xxxx.yyyy.de//transfer

instead of

sftp://xxxx.yyyy.de//transfer

Could this be fixed please?

I often need this for confirmations that the link/login works but ...

Opus doesn't use or understand the sftp:// prefix, it uses ftp:// at the start if both ftp and sftp sites, and the prefix really just makes sure the path is parsed by the FTP/SFTP code and not as a normal path.

We don't have any immediate plans to change how this works, but may in the future.
