Basically, you create the following:
1. One Job with a File Trigger
2. An Email Task where you use the FullPath Variable from the File Trigger as attachment
3. A File delete Task - which also use the FullPath Variable
You should configure the Job settings to:
"Put Job in queue" option checked.
Here is the Variable to the file which can be used everywhere:
{TRIGGER(Active,LastTrigger,File.Result.FullPath)}
You might want to look up the Variable for just the name and one for the folder to use in the File filter in attachment and delete file.
