Exif does not support EML files and I have 1000s of them that need naming.
The subject of each email is located in plain text within the content with the tag "Subject: "

So far I have <file Line:20>.<Inc Nr:1>.<ext> bundled with Remove count 9 starting at 1 which works on some of them, but only a small percentage.
(inc Nr is included incase two emails share the same subject).

But the Subject tag isn't always on line 20.

Is there a way i can extract "Subject: " from the content and us that to rename the file with?

Thank you :)
