I am using the command line edtFTPnet PRO edtftp.exe to send a file.  This particular connection requires a public private key pair instead of a password.  I can get it to work via windows 10 built in SFTP, and via filezilla, but I can't figure out what parameter to set with edtFTPnet PRO for the private key file.  I can't find anything in the documentation specifying what SET option to use in the command line.  I looked for a list of valid parameters to SET via teh command line and I could'nt find that either.
