DeleteFile Method
Remove a file specified by FileName from an SFTP server.
Syntax
sftp.deleteFile(fileName, [callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
The remote file or directory specified by FileName is deleted. FileName is either an absolute path on the server, or a path relative to RemotePath.
If there is no SSH session in place, one is automatically created by first.
