This software extracts e-mails from any number of files that you select. You can choose to automatically remove duplicate e-mails, choose whether or not you want to sort them, and then optionally save them as a file. You can also choose what kind of format to save them in (i.e., .csv file, one per line, or any kind of other delimiter). You can also search for files with e-mail addresses recursively, and include those in your search. It will automatically parse the necessary information.
