I need to drop a file on an External SFTP from Marketing Cloud which I know I can do with a file transfer activity but I can only choose a pre-defined file destination. In that destination setup in Admin, I don't have a place to specify the file path for an external SFTP like I do for the SFMC Enhanced SFTP. Any ideas on how I can do this?
When you choose "External SFTP" as the location type, your Url field should have the absolute path to the ftp folder you need to access.
You can find your folder's absolute path by viewing the folder in an FTP client and right-clicking on the folder to "Copy URL(s) to Clipboard" (that's the option in FileZilla).
